Re: Iver Johnson Revolver Questions
its the hammer spring not the trigger spring. but you have given me enough new information to properly identify. the one patent date of nov-17-08 was only used after 1913. so yours is a large frame third model hammerless. serial number D79131 was manufactured in 1920, there were 3,600 of the third model hammerless manufactured that year. the large frame third models were offered in a 6 shot 32 S&W Long caliber or a 5 shot 38 S&W caliber.
