later 1950-52 models have: a newly cast engine block with a side
mounted distributor along with several other improvements. This one was
not firing when I got it. The wiring harness was trashed and I didn't
bother troubleshooting the problem. Installed new 12v coil, points,
condenser and wiring harness then flushed the tank/carb with fresh
gas...it fired right up.
