RE: 40sr
Good for you on getting those FSR's at such a good price and condition. I have managed to accumulate one .45 FSR (ringed). Most of the ones that I have seen for sale have been non-ringed, which are good engines, but difficult to restore, should the need arise. I might have more than one of the .45 FSR's stowed away come to think of it and I do believe that one is ABN and pumped (Perry). Gotta go check my stash to be sure.
