I've had these two little objects for years, they came from my dad who got them as a kid in the few cigar boxes full of parts he was given by a retired watch repairman.
I believe he also worked on clocks which these could certainly pertain to being too large to be any sort of watch part.
As you can see the larger one is marked with an 8 and the smaller with a 6, they're both 7/8" long.
It's probably a long shot but I would certainly love to find out just what the heck the things could be.
