Its marked C model. You can see the front and back where the float tanks would bolt up. Also the skirt hangers (only one left on both sides). It had Norwegian driving info on the area above the steering sticks. I am like you that going in water is not my idea of fun. I will sick with land whether snow or dry summer. Wish I had extra tracks, but I dont think I will out run the ones on the weasel. I did a link repair by replacing the outer bands with the steel links using SS bolts. I have yet to break them in. I am trying to get the engine to run cooler, 220* is to hot. I will need to up the electric fan to 2500CFM and I would think more air more cooling. I did up grade the engine to a '72 chevy 6 with a powerglide trans.Nice M-29. If it's a 29C, why don't you have the floatation tanks on it? I had one 20+ years ago. Restored it and sold it to a guy who had several of them. I'm in Sacramento and a lot of the rice farmers that were located just outside of town and in neighboring counties bought them up after the war to use for planting rice. By the 80's they were relegated to the junk heap on the edge of farms. I got a lot of parts including engines and spare tracks by offering to haul them away for free. Fun to play with, but I only had the nerve to put it in water deep enough to sink it once. The rest of the time was dry land driving only.
