By model, caliber and serial number.
There is no model number. The model name is Cobra. Are you talking about the serial number?
Quite possible. I own a Model 64B firearm, Mine was manufactured as a"Lakefield 64B" which were made in Lakefield,On manufactured in Canada, Lakefield arms produced various rimfire firearms and was acquired by Savage arms which is why you can go out and buy a brand new 64B firearm under the name "Savage 64B" and as far as I'm aware although savage arms is an American company they still have operations running in Lakefield,Ontario Hope this helps
Virtually impossible to determine caliber by just the serial number.
No such S&W model number.
No way to know the caliber from just the serial number
As of October 2103 I sold one for $225
