Barks' Gyro story with Morte and Ferdie

[lgiver@postoffice.pacbell.net]

Although Barks didn't write any stories with both Donald and Mickey, he did
write a 4-page Gyro story which included Morte and Ferdie.  Normally he
would have used HDL, but for a while the postal rules required at least 2
stories in each comic magazine, with separate characters in each story.
At this time Barks usually met the requirement in the US comics with a 
24-page
Scrooge story (with Donald and HDL), and a 4-page Gyro story.  Many of
these Gyro stories have no other recurring characters except Helper.  The
story with Morte and Ferdie I think was about trapping lightning.
                        Best wishes,
