Joe, Has there been a determination as to the DOM on your Cashmoor? Appears that it was made prior to 1939 as mentioned by the one post. Doesn't anyone have a production schedule on the Cashmoors? The two serial numbers listed are 20003 and 20600 and you mentioned yours being 400 off of mine. Odd that 3 guns are within the same year of production show up at the same time. Nice to know when that year was. EverD..Is your gun set up for 2 5/8" or 2 3/4" chambers and what payload was it proofed. Randy
