50-75
Impossible to answer without knowing who made it.
50-150 or so
Depends, you can still buy brand new ones from china. Authentic though are about 200 years to 100 years old.
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.
As much as a pistol and a shrimp on a boat.
150 or so
For which pistol??
No published sn data.
Savage is one.
Mine is worth 5000.00$ usda.
