Clay James post, may have answered my unasked question. I bought a M35A2 (C turbo) in CA several years ago, it too came from a CA N.G. unit, but it was undercoated. I've only seen undercoating on Marine trucks, but I dismissed it as being added by a guard unit possibly stationed by the coast to avoid rust issues.........but maybe it was an ex-Marine vehicle after all.........I hope!
I had a USMC M35 gasser truck, it was pretty stripped, but it had some good parts that I liberated for my deuce before I sold it off. It had the detachable lifting bars still attached to the rear axle/bed, but strangely it did not have the paperclips, although my understanding the paperclips worked hand in hand with those rear bars.
When ever I get around to restoring her, it will get the paperclips.
I was in the Marines 74-78, I was mostly in towed 105MM Howitzers the multi-fuel deuce was our prime mover in both the 3rd, and 1st Divisions. Whether they were A1s or A2s I do not know, I didn't know the difference back then.
But the Marines definitely used M35s and probably M35A1s, and for sure A2s
