Robb Barnes said:Here is a slightly different twist on the numbers game. Both guns are from the first part of the 1900s and both have the exact same three digit serial number - 146. The one is a Smith & Wesson New Century aka triple lock in 44 Special and the other is a Colt Police Positive Target in 22 WRM. Thanks to Heliman for letting me snag the Colt. I have one other mixed brand identical serial number set and it is a Ruger Blackhawk type 1 flat top 357 and a first year Remington Model 700 7mm Mag from 1962. Both of these guns are serial number 2468.
