What is the age of a rugerm77 with serial number 789-94289 what is the age of a ruger 30 caliber blackhawk serial 50-21687?
Ruger has sn data on their website.
The Blackhawk was not made in 22 LR. If you have one with "Blackhawk" on the frame, you need to call Ruger. There is an almost astronomical chance that you could have a factory experimental, but, I doubt it. More likely you have a Single Six of some type or maybe a Bear Cat. Any of the 22 revolvers can range from 50-400 depending on specifics.
