I have two 5th generation S&W New Departure Safety Hammerless revolvers. Both revolvers are .38 S&W caliber. I know that the 5th generation was produced from approximately 1907 to 1940, but I would like to know the actual year of manufacture. The serial numbers are 244XXX and 249XXX. I will post pictures when the sun returns. It has been cloudy all day.

Any information would be appreciated.
