Thunder Model is set to release its 1/35 scale M1 and M1A1 Heavy Wreckers range by May-June timeframe. The Ward La France M1A1 Heavy Wrecker kit comes out first, out of a series of 6 variants.
Yay! I have been waiting decades for a styrene wrecker! Thunder Models will not disappoint. It will be a complicated model, but it will not disappoint.
Yes ! Of course they have complicated my decision by apparently offering both closed cab and open .Which do I want ? I’ll definitely buy which ever one comes first in case the others don’t appear.
That’s a Big Boy rig fer sure!
. . . couldn’t tell where or when this pic was taken, I like the squared off fenders though.
Seems like Kenworth made a version of this truck. Hefty, hefty, hefty.

I guess the one in the top picture is a Ward La France M1 (a.k.a. Model 1000), not a M1A1, contrary to the other one…
Maybe the very same truck (the s/n looks to be the same…)
H.P.
Correct, the top pic w/rounded front fenders and hardtop (and on the boxart) is an M1 model. The bottom pic w/the angled fenders and softtop is an M1A1. Both Ward Lafrance and Kenworth built both types and they were pretty much identical. Ward Lafrance built a greater number overall.

Didn’t someone here at KM scratch build one of these or was it another truck, it was big, and a beautiful rendition of the truck.

You may be thinking of the Mack NO artillery tractor built by Michael ( 165thspc) . Beautiful model .
