Cajun:
Not an I or J frame Kit gun, serial range only went to 135465.
Not a pre war K22 outdoorsman, serial range started at 632132.
Not a post war K22 Masterpiece, as there is no K prefix.
Not a Model 45 K frame Military & Police, as no C prefix.
Not a M frame Ladysmith, serial range only went to 26154.
If it is a K frame, then the serial number is wrong, probably taken from under the cylinder yoke instead of the butt.
The other possibility is its a .22/32 Hand Ejector, built on the I frame and dating to around 1915, with the serial number on the front strap. This will be a 'true Bekeart' gun, as the catalogued production started around serial number 160000. Prior to that they were special run guns for Bekehart of San Francisco.
