Re: assembly 22 defender
Manufactured by Iver Johnson and sold by J.P. Lovell Arms. The Defender were made from 1875 to 1888 and the Defender 89 from 1889 to 1895.
.22 short r.f. caliber, 7 shot single action Defender no 1 revolver, spur trigger, solid frame, 2 1/4" round barrel, fluted cylinder, birdhead grips, walnut or checkered black rubber, nickeled, marked DEFENDER
Almost sure this is what I've got--I think Hopkins and Allen also made same revolver but with 2 1/2 in barrel
Thanks for any info on assembly or any other info available
