Let's see if it's possible to access one of my old P'bucket photos from an old IHMSA forum thread of one of my favorite falling blocks purchased from a pawn shop some years ago.:
Round about way to get it, funnily enough it was the first image that popped up when I googled ".32-20 Remington Hepburn"....
IHMSA forum link if anybody cares:
IHMSA Forum • View topic - 32-20 pistols with 0311"-0.312" grooves?
ETA: Here's another photo, maybe:

And the Milsurps.com thread from which it came, apparently before purchase. (Try it before you buy it, what a deal!):
BPCR at the range (W/O the blackpowder, so far!) 32-20 Hepburn
(Sorry, lost access to most of my photos when P'bucket went all wonky some time back.)
