OK, here is my third recent acquisition, a Prentiss 19 1/2. This follows the first two, a Monarch (PV Co) 228 and an Athol 613 1/2 that I posted yesterday.
Once again, these photos are in the as-obtained condition, and this one is a bit grimy inside, but the outside is pretty clean, just a bit rusty. Jaw pin is stuck (surprise!), so I'm letting some Kroil work on it. There is about 3/4 turn of backlash, so I'll need to figure that out when I pull it apart. Both jaw faces are pretty good, but the top of the back one has been "peened" so that the junction line with the rear jaw body is almost invisible. Front jaw doesn't have that "feature."
Since there doesn't appear to be any remaining finish worth trying to save, I may try electrolysis on this one. Good reason for me to set it up, I think.
Cheers!
