Friend showed me his new acquisition - a 5-shot exposed hammer break-top stamped 'Meriden Fire Arms', ser #307302. Sorry no pic and I may never see it again. I've never heard of Meriden, but it looks like an Iver Johnson and appears to be a .32 s&w - possibly black powder? It is in rough condition with flawed timing and I discouraged firing it. Any info at all on this old revolver?
