Hi There,
As Mike said, you have to order a Historical Letter in order to know when
it was Sold. The date of manufacture and the date a revolver is sold can be
a decade or more apart. Unfortunately, S&W didn't keep records on when
the revolvers were made. Only when they were sold.
The NM#3 came out in 1878 and your frame was probably made in 1878 or
1879. Now S&W's process was to first manufacture the frame, fit grips to it
and place it in inventory. Later when a work order came down from the sales
department, the assemblers would check out a frame, gather the necessary
parts and go to their workbench and assemble it. When the parts were fitted,
it was disassembled and sent to the polishing Dept. for final polishing and the
finish (blue or nickel) applied. Also, if a revolver was to have special treatment,
(like engraving and/or silver or gold plating, etc.) it was done at this time.
There wasn't any order in which frames were check out for assembly and
finishing. Hence the order of completion wasn't sequential by serial number.
Also, some revolvers were assembled 'for stock' and would go into the ware-
house and sometimes not being sold for over a decade. So a Historical Letter
will only tell you when it was Sold and not when it was made.
It has been established the ALL NM#3's are BAFTE Antiques and not restricted
on the Federal level.
Cheers!
