LGS called me yesterday about some items a lady brought in from her husbands estate. I had bought several firearms from that consignment. At any rate wound up with 2 Model 52 Magazines and a 22LR cylinder for $75.00 that the LGS thought might be for the Model 53 I bought. Turns out it is not. Serial number on the cylinder is 6K6450 so I think that makes it a 1974 for a 17-3/18-3? Very good condition complete with extractor and rod very slight turn line and great bluing. I have no use for it so am wondering what it might be worth and what it would fit.
