Impossible to answer without knowing who made it.
Depends, you can still buy brand new ones from china. Authentic though are about 200 years to 100 years old.
Which Model are you asking about.
Need to know if it is a revolver or pistol. What is the barrel length? What markings are on the frame/barrel? What type of finish? What are the grips made out of? Pictures are a big help. Does it have the original box, manual, etc.? Without this information it would be a pure guess.
what model ??????????
No such model in the Ruger line.
The model 1911/1911A1 Governmental pistol with that serial number was produced in 1944.
can you tell me the model ??????????
Would need the model to answer.
1974
The model 100 was made between 1935-1941.
I've had an Iver Johnson Model 844 (the gun says Patent Pending right beside the model #) since about 1966 and it looked old when I got it (but was in good condition. My Dad (at that time) said he had one just like it when he was a boy and he was born in 1915.
