Alrighty guys so years ago i did western shows at biker ralleys and i picked this little guy up, its sat for years and when i took it out the other day i noticed the trigger wasnt acting right. Ive got it all torn down and decided to do a little research on it but i cant see a seriel number under the grips to give me an idea what ive got here. There is a flat leaf hammer spring and the barrel reads "iver johnson arms and cycle works fitchburg mass. Usa patd apr 6 86 feb 13 87(?) May 10 87(?) Dec 26 98 pats pending" not 100% sure those are 87's but thats what it looks like, the butt is marked 38027 and above the chambers its pretty warn but i wanna say its 42088 thanks in advance for the help guys! And anyone know a trick for replacing a trigger spring without hunting a gunsmith down?
