Used camera body Cap S211751

Not sure what camera it will fit. Diameter is approx. 45mm. Maybe for Olympus PEN half frame? I don't know. Please look at the pictures.

Item has been used with little signs of cosmetic use, with some scratching from normal use. But it is not damaged in any way, no cracks or dents. This lens cap is fully operational and functions as intended.  I would rate it a 6.5, on a scale from 1 to 10.
