The serial number is the same on the bottom of the grips. It has no letters stating it only numbers, 935xxx. But the number inside the crane is 2 two digit numbers.Welcome to the forums from the Wiregrass! It looks to be a Cogswell & Harrington conversion of a British Service Revolver that was originally chambered for .38 S&W, not .38 Special. They usually stamped their names on the frame...could be underneath the grips. Likely, the cylinder chambers have been reamed for .38 Special as it was more prevalent a cartridge in the US. The original barrel was 5" and has obviously been shortened and the extractor rod locking lug was cut off leaving the rod exposed. The original grips were originally smooth and were checkered by C&H. The Tyler T grip adapter rounds out the conversion. The gun has very little collector value, but it does have value as a concealed carry belly gun...if it is legal.
There should be a serial number on the butt of the gun somewhere for it to be legal. 935xxx IS a valid SN from late 1941 or early 1942 before the V series serials began. If that number came from the yoke (crane), it is probably an assembly number used during manufacturing. That is not a valid serial number. So, look on the bottom of the butt frame and, if no number, under the grips for a serial that is in the 900K range or starts with a V.

These were typically a 5 inch revolver in 38 S&W, not 38 Special but yours may have been reamed to take 38 Special when they cut the barrel off to make a snubby. The front locking point for the cylinder was on the part of the barrel that was cut off
