This Model 14 is an interesting gun, unfortunately not sure how it'll letter, probably as an original blue gun. Bought from a local collector (and past President of the S&WCA), this gun is my only 8 3/8" gun currently (got rid of the longer barrels over the years), and is unusual with the nickel finish. The gun is marked with an R-N in a rectangle box under the grips.
Neat gun, it caught my eye and displays well, not key to the collection but neat nonetheless. Features include Target hammer and trigger, blue ramped front sight with red insert and trigger stop.
Note - Nickel M14's do exist but are very scarce.
