Hi, recently aquired an Iver Johnson Hammerless Saftey Trigger 5 shot Revolver.
I'm looking for any and all info that may pertain to the year of manufacture as well as number made that year.
heres anything that may help the experts:
double top post latch, leaf spring hammer spring, saftey in the middle of trigger, owl head on grip facing barrel, and free spinning cylinder
printed on top of the barrel spine:
[X] IVER JOHNSON'S ARMS & CYCLE WORKS [X]
FITCHBURG MASS. U.S.A.
printed on the bottom of handle:
PAT'D APR.6.86. FEB.15.87.
[X] MAY10.87.MAR.13.88.AUG [X]
25.96. PAT'S PENDING
under the left grip is:
J 13117
under the cylinder bridge as well as the side of the trigger guard is:
13117
and heres some measurements might also be helpful:
barrel length: 4 inches
cylinder length: 1 3/16 inch
diameter of bore: 3/8 inch
it appears to originally been blued, but has worn off the barrel, cylinder, and grip area. sorry for bad pics all I have at the moment is my cell phone.
also apone taking it apart, only two things seem to be wrong mechanically.
1st being the part with the arrow pointing at it, the ring that holds it to the trigger is broken/missing
2nd being the spring for the firing pin. pin just comes in and out by tilting the frame forward or backwards
