I recently purchased a blue CM with one stainless steel mag, the zippered pouch and the manual. The left side of the slide has 'Detonics .45 ACP Pat. Pend.' The right side of the frame has '2086'(serial #) stamped above the trigger. These are the only markings on the pistol. The main spring housing is arched with a lanyard loop on the base. It also has wooden grip panels. There is no address or city. It appears to be unfired or fired very little.

Any help with the identification is very much appreciated.
Thanks
