Used Lens Cap H122052 66mm ID

Not sure what brand it is nor what mount it will fit. It fits Pentax 645 mount, but it doe snot lcok.
Lens Cap is in excellent condition, inside and out.  There is some light scuffing and scratches from normal use.  Cap is fully operational and functions as intended.

I would rate it an 8 on a scale of 1 to 10.
