Here's one of the D2 pulling a weight sled at a tractor pull.
It is very interesting to me that it can pull nearly its own dead weight.
The RCAF used small crawler tractors such as these to pull snow compactors onthe BCATP airfields in WWII.
The fellow driving it is my son Alan who is also the proud owner of a '43 F15a.
