I understand it was Colt Colteer.
Depends on when it was manufactured. The original models were single action; later models were double action only (DAO).
about 1907
Based on serial # 313213, It was manufactured in 1910. (312000-315999)
and the question is: .........................????????
1908 if it is a Single Action Army
@1968
I assume your single action is pre-war ? If so, then made about 1907. As to the caliber, check markings on barrel. that should give the caliber.......
Sorry, but you have a bit of a contradiction in terms. Western style revolvers are single action, not double.
Pre 1899
Can't be answered without knowing who made it.
per proofhouse.com,around 1959
I inherited a .22 Revelation Model 100 single shot. It is manufactured by Western Auto Supply Co. and as far as I know it dates to the mid 1900's 1955ish.
