I.N.A. .38 Special Tiger (Brazil)

I bought this gun in the early 1970s from a friend for $50 including leather belt holster, cleaning brushes, about 6 boxes of .38 ammo including .38 SP police wadcutters and a few others.

He had about 10 kids and was always adopting more, wanted to get rid of the gun. I think a son or two were cops, may have come from them?

MY QUESTIONS, is I.N.A. (INC NAC DE ARA on grip buttons) still in business? Can you look anything up about the gun with the serial numbers like mfgr date, etc. anywhere?
.38 Special on barrel, tiger image on frame, about 2 3/4" bbl, 5 shot revolver.

I've only test fired it a few times, felt pretty good on target about 15 feet. I just have it as another house gun. Is it a good gun? Any idea on today's value, it's looks good, pretty fair condition.

Your comments please, thank you, mjp.

I found some youtube videos on the INA .38 Special Tiger.

I agree with most of what they have to say about the gun including the S&W comparisons.

I still would like to find a site that you can plug your gun S/N into it to get the details like when it was made, etc....if it even exists!
