Thanks for the replies, guys, and your insight. I realize this knife wasn't meant to be a showpiece. On the other hand, a big part of my collection consists of examples of "old workhorses" that came off the line gorgeous and stayed that way. In most cases, I have another example of the same knife that I carry and use.
My favorite such knife is my old Kabar 1002 Liner Lock, a utilitarian if there ever was one, with wood handles and brass bolsters, but perfectly crafted and finished.
Anyway, what I was looking for was a fine example of a 787. If the lack of a half-stop is intentional and the slightly botched handle is typical, maybe I actually have what I was looking for.
Bill, the bolsters are exactly as you describe. I didn't mention before that all four of them show these "jig hafts" that you mention. They do, in fact, follow the contours of the jigging. I think I'll call them a sign of a well finished knife rather than a flaw.
Since everything else about the knife is perfect, I think she's a keeper. (I just gotta smooth out that mess around the pin, though.)
To be fair to the old girl, here's how she looks when not exposed to a microscope. She still wouldn't want to be photographed beside my Queen Muskrat, but she does look pretty good.
