I've got a floor shift 3-speed transmission with the casting number 590715. Supposedly came out of a 1946 Chevy truck, however it doesn't match what's shown in the shop manual--it's a lot beefier in shape and weight. Did Chevy offer a heavy duty 3-speed?

Can you still call it a barn find if it's your barn?
