The original Harvey Kay Chuk was made by Jim Harvey & Don Cassavant of Lakeville Arms Co., Lakeville, Conn. They were made on model 17 or 48 guns either from the customer or a new gun.
They redesign the firing pin to a center fire condition retaining the original rim fire hammer. There is no records of how many guns they converted. Later the rights were sold to the Bennett Gun Works, Delmar, N.Y. Bennett stamped their guns on the barrels.
Mgibson - You mentioned "single action" so I will assume the double action sear has been removed form the hammer. Also it sounds like the frame has had the barrel replaced with a Jet barrel. I agree with the prices Rad29 mentioned however, considering the alterations to the original model 48 I would say the value is very close to the low end of $700. IMHO! ! !
You mentioned two numbers that appear to be serial numbers! ? ! The serial number on the bottom of the butt frame is the number that would be used as the guns serial number. I would like to see pics of this gun(please)!
