I used to have an old 80 pound self cocking crossbow, and the holes match up to the ones on the bottom there.
The only thing is the self cocking ones have a small point that comes out near the end of the crossbow to grab onto, and a small lever on the back instead of the pull.
I think it may be drilled as mentioned before. I can't really see them mixing and matching off what seems to be a 20$ flea market special and a 30$ flea market special.
as far as the glasses go.... no clue. you might wanna check with blufive. I think he works in an eyeglass place, and may have an idea moreso or at least a catalog to dig through.
