The Caterpillar D7 crawler and bulldozer from World War 2 | Armorama™

This truly stunning diorama and build of the Caterpillar D 7 Crawler and bulldozer and how it helped during World War 2 helping the Allies change the outcome after D-Day by building new airfields, allowing the allied bombers and fighters attack the retreating German army repeating the same action of building new bases and airfields over and over again

Here is my iteration of the Mirror CAT D7:

Additional real wall detail added to the radiator.

Added fuel injectors and the underfloor control linkages. (Yeah, I know they will never be seen on the finished model. (But I know they are there!)

Added some really nice Tamiya etched winch brake bands, picked up off some left over Dragon Wagon parts.

Here is what I was really shooting for based on the reference photos below:

(This tractor, trailer, bulldozer combo won “Best Armor” at the Louisville IPMS Regional. I kinda like winning Best Armor with Military, soft skinned, wheeled vehicles)

p.s. I could have gone for the armored dozer but all that armorplate just hides too much of all that very nice mechanical detail!


Beautiful job Michael - I know the Mirror D7 is lacking in some ways but you seem to have overcome…

Nice job. It looks great. I like it on the trailer too.

Addendum - another one would look good towing an Athey trailer - just sayin’ …

Oh, I agree.
