That is a pair of supreme Squack rifles. I have an old Pre-A speedlock that I have used for squirrel hunting in the past. At some point in its past, it had the bbl cut off to precisely 22-3/4". It is not a pretty rifle and was not a sporter, but the short bbl does give it a carbine feel and makes it a handy little hunter. For the last few years it wore a B&L BALVar scope and was tasked with bench rest shooting in my club's weekly repeater/sporter factory rifle matches. It won so much that now nearly all of the regular participants are shooting 52's. I recently acquired a pair of twin 52B's. I put the BALVar onto one of them so the Pre-A is currently topless. I am toying with turning it into a NRL-22 rifle. These days I hunt with a CZ452 American and a Savage MkII in 17M2.
