When I was seven or eight years old, I received a Golden Book of "Out Of Scale". This was probably 1950. I was really fascinated by ride-on stuff even then. I remembered seeing the cartoon in about 1951 or 1952 at the theater, then later on on the old Disneyland program. At that time it was shown in black and white. I looked for many years to get a copy of the cartoon and eventually it was brought out on DVD as part of a collection of programs from the old shows. I foumd it on Amazon.
This book actually started my life-long yearning for a ride-on train. In 1980 I finally got the drem fulfilled when I purchased my Gene Allen live steamer as a kit. While building this, I started my rolling stock-a caboose, gondola and reefer.We NEVER grow old!
I DO remember the Chip and Dale book and the island with the stored acorns.
"Out of Scale" is on the DVD of "So Dear To My Heart", the story about a yoing boy raising a black sheep in 1890's. There is a train in this movie and the station that was used became Ward Kimball's station in his backyard for his narrow gauge railroad in San Gabriel, CA. If you notice, the station in "OOS", is a facsimile of the Grizzly Flats station used in the So Dear To My Heart movie. Lots of railroad connections with Walt and Ward Kimball!
