There are a lot of Ithacas with choke devices although more have Poly Chokes. Probably because of field use. Ithaca's pumps were not real popular for target games. I will try to find my M-37 RD with a Flex-Choke. You wind it up and it tightens choke with each shot, eg. IC to Mod to Full. Will post a photo if I can locate it. Well, in the meantime, here is a scan of the ad.
