The attacched photo shows J.P.Hayes' personal choke reaming tools, the 16ga., 20ga.,and 28ga. attached to their rods. The taper sections of each of these reamers is approximately 3 1/2" long. The more open choke the machinist desired meant the barrels, attached to the lathe carriage, were moved further inward. The greater diameter of the choke, which is obviously the inside, is largest dimension of the reamer.

I'm at a loss to understand how Remington performed the choke reaming operation from the muzzle end, unless the reamer, inserted into the breach end, was drawn inward from the muzzle end. It would not be possible to insert the tool from the muzzle end.
