I have a Smith & Wesson 29 - 2 nickel plated 6 inch barrel with the serial numbers N68XXX15 and on the yolk there are numbers 56943 F4 and on the butt there are numbers 5461 with the letter j circled and the letter N circled what do all these numbers mean and could anyone tell me what year is revolver this was made in Thanks

No doubt fitters or assembly numbers. The N stands for nickel

 

[Laketime]

I believe that would be 1980
