In regards to the lack of, or mixing of scales for O scale vehicles; one vehicle always stood out to me. The 1956 Ford F100. This truck is a popular model and is produced in 1/43, 1/48, and 1/50. I have always thought that the scale models of this truck looked out of scale. In the real world, the F100 has an relatively large cab when compared to other manufactures. I did a little research and it seems that the Ford 1956 F100 cab is nearly identical in size and shape to the F700-900 series cabs. Using this fact, I have begun a project to use 1/43 scale F100s to create "comfortably appearing" 1/48ish dump trucks. The attached pictures show my progress. Note the mock up using a paper dump bed. That bed would be approximately a 16 ton coal load in 1/48 scale. I have some wheels from Don White and some other details, and will have to build a frame, but I think this cross scale experiment will make a fairly reasonably believable 1950s-60s era coal dump truck.
