I have one sitting on my lap at the moment. It is a tiny (hand sized) little .22 cal. revolver. Six shooter. It is double action but the action is VERY heavy and thus you tend to need to pull the hammer back if you would like any hope of hitting what you aim at...a prospect which is pretty much a pipe dream anyways. It looks rather cheap but in good used condition could probably sell for $60 bucks.
The barrel is cylindrical but it has a sight that runs down the top of it that is rectangular. The handle grips are plastic made to look like a dark stained wood. The RG is engraved in the plastic on either side. On the left side the caliber and model number is imprinted into the metal behind the chamber. The chamber is opened by removing a screw under the barrel at which point the chamber will simply roll out to the left side allowing shells to be inserted. The screw that holds the cylinder in while in use serves well to push out the old shells (a necessity as the LR .22 shells can get lodged in there pretty good sometimes...they don't just fall right out). There is NO hammer block so I would recommend always keeping the hammer on an empty chamber. Actually...I would recommend not owning this dangerous and cheap piece of crap.
A large revolver
Pretty much the same as any other revolver or semi-auto.
Need to know iif its a revolver or semi-automatic and the caliber.
probably a model 17 or 18. look in the cylinder frame area for model number
Depends on the model. Look in the crane area.
it looks exactly like a vietnam era m16 in .22 caliber
To distinguish between the .32 caliber and .38 caliber Iver Johnson revolvers, you can look at the markings on the barrel or frame, which typically indicate the caliber. Additionally, the size of the cylinder will differ; the .38 caliber revolver will have a larger cylinder to accommodate the larger cartridges. If you have access to the ammunition, comparing the cartridge sizes directly can also help identify the caliber.
Look at them and then find a copy of the Blue Book of Gun Values
Revolver
It's a revolver.
You have a single shot pistol which is built to look like a revolver. The cylinder is actually a breech block which is hinged at the bottom and pivots to the left, I think. Look for a small release button or lever to unlock the breech block.
I don't believe it's a Winchester, you might want to look closer.There was a spanish made revolver chambered for 32 Winchester, could that be it?
