Well here it goes...
I ended up with this revolver a few years ago and have never fired it. It does have a few marks on it and the only other thing in the box is the papers and six extra primer nipples. I'm curious as to when it was made and what anyone here might think it's worth. I'm not an expert on blackpowder.
Thanks

Best i can determine, Armsport was an importer in Florida which ceased to exist in 2000. I'm thinking the pistol is a replica made in Italy. b

I'm thinking that import laws require the Country of manufacture to be stamped somewhere. Maybe not. Nice looking revolver though.

Found this on another forum: The barrel should be marked "Armsport-Inc.-Miami-Fla." & "Made in Italy-20C".

Also keep in mind when you are working up loads for this revolver that your brass frame will not stand up to the same levels of pressure that the same pistol with a steel frame will. Back in the late '70s and early '80s many importers used to import a lot of revolvers with brass frames. They do look prettier to some but were prone to frame problems when used with loads designed for hunting or higher pressures. I have a good friend on Monaville, Texas that loaded his the same as I did my steel model for hunting rabbits and hogs. Bear in mind we had revolvers of the same model and from the same manufacturer, just his was in brass and mine was in heat treated and blued steel. On the third shot during our last hunting trip with the pistol his frame bulged out at the rear near the hammer strike hole. The gunsmith it was because of the steel cylinder hitting the frame. He was lucky as he did not get hurt.

Man...I never thought about that brass frame...kinda glad I never tried to shoot it...

So what I can conclude is that this gun was manufactured in Italy during the 80's? With that being said, does anyone think that this gun could be of some collectible value? I have had it in a display case since I got it and I think it's kind of pretty with the brass frame.

I hate to be negative but they are not a very notable piece from a collector's point of view. Back in the 80's firms such as Navy Arms and Dixie Gun Works imported these by the thousands and if I recall correctly they sold for somewhere in the $75.00 to $125.00 range. At some of the very early cowboy action shoots and civil war reenactments they were the thing to have as they were cheap and easy to find. Then as both of these sports matured the participants moved on to better made replicas. That being said, they are nice for plinking and close up small game hunting. But like in hunting where a 125 class buck is one hunter’s trophy and another hunter’s cull, if you like the piece then display it with pride. After all, the only thing that really matters is what you think isn’t it?.

You know...
I've seen cylinders for these style guns that fired a modern style brass cartridge. Do you think the brass frame could handle one of those?

Over the years the quality of these pistols and the materials that they were manufactured from improved from shoddy at best to pretty decent. Not knowing exactly where your falls into this process I would recommend that you have a competent pistol smith take a look at it for you. However, I would think that the pressure issue would apply to modern ammo just like it would to stiffer blackpowder loads. Brass is a much softer metal than steel and any time the two interact with each other the steel is eventually going to win the fight. In other words it might shoot fine at the beginning but eventually the continued galling and beating of the brass by the steel cylinder is going to cause a weakness. When and how long that process will take to cause a problem is anybody’s guess.
Back during the later part of the war of northern aggression the south ran short of steel with which to manufacture firearms and began replacing components with brass. If you research the web you will find writings mentioning the brass framed revolvers blowing up or wearing out due to the “hot” combat loads that were used by the soldiers. I believe that the museum in Vicksburg has several samples of these pistols that show this had happened during the heat of battle.
As to using modern ammo in it, remember that not all .44 caliber ammo is actually .44 caliber in size. The current offerings actually range from .42 to .46 in diameter. Before considering converting it to modern ammo you probably need to have the barrel and frame miked to measure their true diameter in order to determine what it can be converted to. Then don’t forget the pressure issue. I know the .44 mag will be too much for the frame.
Please remember, I am not saying don’t shoot the pistol, all I am saying is be conservative in the loads you use until you are certain that it is safe to use heavier loads in it. I used mine for rabbit hunting for many years and never had a problem because I kept the loads in a safe range.
