It is an Argentine Colt made under license. This one was manufactured in 1949. The Sistema Colts are high quality and this one looks to be in good condition. My two cents.
I'm in agreement with Troy9749. I wouldn't own one personally. Those that have them and are satisfied with them great, but I stick with quality firearms that I can depend on. If you can get $500 for one it simply reproves what PT Barnum said all those years ago.
I had heard about the ODT from several friends but have just gotten around to checking it out and joining. I have the feeling I'll be spending a lot of time here. Longtime NE GA resident currently making my home in Athens, aka The People's Republic of Athens-Clarke County. Gunsmith, NRA...
