I would like a valuation on this please. Vintage .177 BSA which I think is the Light or Ladies pattern, barrel 18 1/2 " overall 42" even pitting over entire surface, rear sight element missing, I would say main spring replaced at some time as it's round section and the gun shoots well so mechanically good. No splits in wood and BSA logo on pistol grip clear but none visible on metalwork. S/No. 6498.....Pictures below.
