0029 The Mummy's Ring. First issued in 1943 but for its second edition in 1965 Western asked Barks to redraw pages 1, 16, and 17.

0108 The Terror of the River. The height of some of the panels on the first page was shortened so that Western could make room for an ad at the bottom.
The Firebug. The last two panels of the story originally showed Donald in jail for burning down the court building. Western regarded this conduct as being Un-Disneyish and had another artist draw a different ending.

0203 The Golden Christmas Tree. Western asked Barks to make the final fight scenes between Donald and the witch mellower. He did so, but Western decided to use the original panels with a slightly altered text, anyway.

0495 Barks made three alternative versions of the pirate-in-the-box cover.
Barks decided to remove a half-page in the story about the water tank Money Bin.

1184 Barks produced a total of 32 pages for this Gyro Gearloose issue but only 29 were initially used because Western needed space for ads and two one-pagers from another artist. A later edition contained all of the pages.

1239 The front cover originally also showed Gyro but he was removed before publishing.

26 Barks was asked to create a comic book story from the upcoming Disney animated short Trick or Treat. He drew 32 pages - partly based on drawings from the film, and partly new material that he dreamt up himself. The loveable monster Smorgasbord was an invention of Barks'. The original splash panel, which showed the witch flying over Duckburg at night was not accepted because none of the ducks were present, so Barks had to draw another one. All Barks' pages (including the original splash panel) were later published.

51 Barks drew a one-pager of Scrooge buying a hat but Western shortened the gag to a half-page.

52 The Lost Peg Leg Mine was originally scheduled for WDCS203.

106 Barks drew two versions of the front cover called Ambush of Thunder Mountain. In the non-published version the foremost nephew is bouncing on the drum with his behind instead of using his legs.

08 Originally, Barks produced 32 pages for the main story about the petrifying ray machine but he was not happy with the flow of the story so he shortened it to 28 pages. The unpublished pages still exist.

12 In The Golden Fleecing Barks was asked to redraw panels 1 and 3 on page 16. The reason given was that he had drawn too many Larkies in the panels, and too little was seen of the ducks.

13 The story Land beneath the Ground was originally 32 pages long but it got shortened to 27 pages in the first issue. Later the story was published using 29 pages. The 3 remaining still exist.
The 4-page Gyro story starred the nephews helping the inventor but Barks was forced to alter the kids into Morty and Ferdie from the Mouse universe. This was caused by a regulation introduced by the U.S. Mail, saying, that comic books sent as second class mail (for the subscribers) should contain at least two stories with different characters in each. The nephews were already present in the main story of the comic book.

14 The 4-pager about Gyro trying to invent in peace despite harrassment from the neighbour kids had Donald Duck in a visiting role, but Barks was forced to change him into a new character instead for the same reason as described in U$13.

17 The front cover depicts Daisy in the role of a fortune teller examining Scrooge's hand. Barks originally used a human lady but Western rejected the idea.

22 In the 26-pager The Golden River Barks changed the flow of the story somewhat after it was finished. He added an extra 8 panels (a balloon gag) between pages 4 and 5, but still managed to keep the story at 26 pages by deleting 9 panels from different pages and adding 1.

31 The one-pager The Secret Book was changed by Western. They shortened the sixth panel in order to make room for an editorial commentary.

32 In That's no Fable Barks changed panels 5 and 6 on page 5 before publishing. The original panels still exist.

33 In the one-pager Tree Trick Barks thought he had the good foresight to draw only 7 panels instead of the usual 8, because he had previously experienced Western shortening one-pagers from 8 panels to 7 so they could make room for ads and such. But this time Western needed a full page, so they stretched the last panel to fill out the bottom of the gag page.
In Bongo on the Congo Barks mistakenly gave Donald a pince-nez, like the one he gave Scrooge. This was corrected in later issues.

34 Mythtic Mystery was originally a 16-pager but Western deleted two pages to make room for ads. The pages have since been lost.
Chuckwagon Derby was drawn as a 10-pager but - again - Western shortened the story by deleting one of the four last panels to fit in an ad. The three remaining panels were then cut in width so that the whole page ended up being just a 3/4-page.

46 The nephews' faces on the front cover were redrawn by a staff artist at Western.

50 Rug Riders in the Sky was finished as a 17-pager but Western removed one full page (probably around page 13) in which the ducks are hunting Magica de Spell in the desert. The page has been lost.

51 How Green was my Lettuce was also tampered with by Western who removed panels mounting to a total of 2 pages. They have since been restored.

54 The front cover for The Billion Dollar Safari was drawn with full backgrounds by Barks but they were removed by Western.

64 In Treasure of Marco Polo the disguised prince Char Ming was garrotting two enemy soldiers (page 16, panel 2, and page 21, panel 7) but Barks had to modify the action by just showing how the prince was jumping the men from behind.

042 Kite Weather was originally drawn as a 10-pager with 6 panels to a page, but Western changed the format into a 7-pager with 8 panels to each page. (The observant reader might want to know what happened to the missing 4 panels (from 60 to 56) following that action, but Western simply stretched the existing panels to fit the new format.)

063 Western provided the ducks with haloes in the last panel of the story about a missing dollar bill.

140 The front cover with Donald golfing was drawn showing the angry duck with red eyes. Western changed them to black.

142 On the front cover Donald is seen feeding pigeons. Barks originally drew the cover with some background which Western chose to delete.

156 The fingerprints on the bath towels on the front cover were not drawn by Barks.

157 Barks had second thoughts about the ending of the 10-pager describing Scrooge and Donald climbing Old Demontooth for a wager. Originally, he ended the story by letting Scrooge scoff at Donald for not being able to beat him, but that would also mean that the stairs of money would have been a long real-time enterprise, which Barks realized would have been impossible to complete in the little time the story takes to act out. Consequently, he decided that the whole wager should be a dream instead.

160 Western redrew Donald's face at the front cover in order to make him look sicker.

174 Again, Western redrew Donald's head on the front cover.

175 In the taffy story Barks originally drew 1-1/4 pages in a hospital but he later found that the action did not add to the story's flow and the pages were deleted. Instead he inserted a scene in which Donald is visiting the Zoo. However, the hospital building can still be seen in some of the story's published panels.

247 The Madcap Mariner was originally a 10-pager but Western decided to delete one page (probably page 9). Barks later recalled that the deleted page contained the best gags of the story.

249 Again, Western deleted one page in this 10-pager named Stranger than Fiction (probably between pages 8 and 9) to make room for an ad.

289 The Donald gag at the front page was partially drawn by another artist.

FG1948 Donald in Toyland. Some of the ducks' facial expressions were changed due to a request from the Firestone Company. They did not want the ducks to look too sulky or angry. The company feared that a Christmas story like that might attract complaints from parents.

KG Donald Duck tells about Kites. The story was made in three versions as it was ordered from three different power companies in USA. The versions have only minor differences.

LCB Donald Duck and the Boys. Barks drew 48 new illustrations for this children's book which was based on his story in WDCS074. However, in the book Barks altered the teeth of the Wild Woman from Borneo from being pointed to being nonexistent. This is quite bewildering because the text clearly states that Donald comes to collect for a dentist bill on which she owes money for having had her teeth sharpened. When he changed the appearance of the lady Barks obviously forgot his own story in the comic.
