Iver Johnson Started importing Uberti 1860's about 1974-77 ...they were in the white and finished @ the old Iver Johnson in Fitchburg, Massachusetts.
At that time 1977 , Lou Imperato leased the factory and entered into an agreement with COLT to spearhead Colt Second Generation black powder series in 1977 that was the end of the Iver Johnson roll stamped guns , and the start of the Black Powder so call Black box 2nd Gen guns & the 3rd Gen. Signature Series guns.
Lou Imperato is also the founder of Henry Repeating Arms .... Lou passed & his son Anthony Imperato runs it today.
So the Iver Johnson guns had about 3 year run , and a kinship with Colt/Uberti's
In its day, Iver Johnson made Bicycles , Motorcycles, and guns....during WW2 they made Garand's, M1 carbine's and 1911's
I say "if" its as you say " nice condition" ...bore is bright , and functions well .... see if they'll take $250 cash.
Fit the new wedge & check the Arbor fit... and you did good !
I'd probably buy myself .
