Not sure what brand it is. Nor what model it might fit. Inner diameter is 40.6mm and 41.8mm. Outer rim is 58.6mm.
Sorry I don;t know what camera it might fit.
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 an 8, on a scale from 1 to 10.
