I have a set of replacement cases that have never been stamped. The corner of the mag/generator mount has a broken corner. I think these may be '46 back and modified for the later scaper setup. I know nothing about Indians. Bought this to trade for some HD stuff and it didn't work out. I have a set of new cylinders and pistons that came from Kiwi. $1500.00 plus the ride for it all. No title, just a BOS. Seadub
