Hello Joe,
The blade is stamped:
BUCK
105
U.S.A.
The knife was given to me by my father in '74 or '75 when I was 13 or 14 years old. It was my first "real" sheath knife. I still use it all the time and it's in great shape.
IMO, as far as the spacers go, two at each end look better. I agree that the ones that back up to the black handle are harder to see, but I know they are there.
It's all in the details!
Best,
Tom
