These guns were made by a company in Germany (still "West Germany" then) named Weihrauch. Strangely, despite their long history of making automatic pistols, the Germans made quite a business out of producing inexpensive revolvers for export back then. They all used cast zinc alloy frames, which was a new technology for making pistols at the time. They left most of the inexpensive automatic pistol trade to the Italians and Spanish, maybe because those countries could make low-priced pistols with steel or aluminum alloy frames due to lower labor costs.
The Weihrauchs were about the best of lot, IMO. Weirauch sold most of them under their "Arminius" trademark, but they supplied some to other companies, and that is what these Titan Tigers are. During the late 70's and early 80's (IIRC) the German unit of currency at the time, the mark, soared in value compared to the US dollar, and they could not compete on price any more. Most the German makers of these revolvers dropped out, but I think Weirauchs are still made now. But I haven't seen any for a long time, so I could be wrong. The tradename of their later, improved guns was "Windicator", I think.
I have a 7-shot 32 S&W Long 4-inch barrel Arminius revolver with adjustable sights made in the early days, and it's a decent gun. It's not pretty, but its accuracy is OK. The fact that 32 Long is very low powered probably helps.
PS - Here's a test firing video of a 2 inch 38 Special Titan Tiger":
The maker does not pronounce "Arminius" the way I do, but I have no idea if I am right.
