Remington-Smoot no.2 Repair #1

I bought this revolver knowing that it is missing the ejector retaining ring. This is part: "d" in the Patent drawing, and can be seen at the lower right hand side of the page above.
 

As seen in the Patent drawing above, I have since learned that the ejector retaining ring is attached to the cylinder base pin.

Without a quick & simple way to remove the cylinder, a black powder cartridge revolver would not be popular among the gun buying public.

It is also used as a handle to pull the cylinder base pin out while disassembling this revolver as described in the "directions for use" which is found  on the original box.
