Tested that the shutter opens and closes. You crank the handle and the shutter clicks shut and takes a moment to open again. I don’t have film to fully test but it seems to be operating but I do not know how to exactly use this camera. Therefore, am selling AS IS. Please note that this is missing camera lens cover and there are some scratches to body consistent with use. Battery not included. I don’t know how to find aperture so please see that I listed what was on lens
