Definitely not a '37, or in the 30's. I am uncertain it is a Chevy or a close relative. But, the tranny number shown in the photos does appear to show a BowTie symbol in the casting as do the other data plates.
Some close up photos of the engine and cowl, especially any numbers on the engine block might provide additional clues. The wheels appear to be post World War 1 and pre late '20's? The missing cab might mean it was made of long ago disintegrated wood? The dash and front clip sides and fenders are different from the very few late 20's Chevy trucks I have seen. Having said that, my experiences have been no where near enough to defend my opinion. My guess is, it was made between about 1920 and 1927 and most likely in the mid 20's.
