Help dating three smiths?

I have three older S&W revolvers that I'd love to know how old they really are if anyone can help.

1) Model 19-3 4" serial 9K2xxx

2) Model 36 serial ABUxxxx

3) Model 36 serial 529xxx

High Vel: there are others with more precise info than mine but what I have indicates: 1975, 1983, and between 1964-66.

Looks like ulflyer and I aren't gonna argue over THIS topic. (Not that we've ever differed previously. :p )

Hey Johnny: I just read what my piece of paper says. Somebody gave me copy a good while back with a lot of info about Smiths on it. Don't even know the source of it, but its generally pretty close. Some of them you hafta guess a little...others are right on.

I have nothing against sharing information, so long as it's not for profit, so please don't think I'm going on about that aspect - - -

BUT, if you care about S&Ws a-tall, the SCS&W is really worth having. Check on the 'net, and you can find copies for under $30. Be sure and get the second edition - - This is the latest, and even it is missing some of the latest stuff.

Best,
Johnny

Thanks for the info. I guess I really need that book!

How about a mod 36 50J3XX???
