Konica 38mm lens cap

Just as it says on the tin :)
A lens cap for a Konica camera with a 38mm lens. A replacement for if you (or a previous owner) lost the lens cap (which is probably a given after 50-od years).
Also makes it so the battery doesn't get drained as the camera is only off when the lens cap is on ;)
Not the most snug fit, but will protect the lens from dust and debris when walking around. You could always add a layer of tape or something on the inside in order to snug up the fit.
