If you serious about getting into the Super 23 world virtually all the "mint" ones are gone. This one is fine, realize you will have to sink 2 to 300 into a good CLA by Clarence Gass (in Kansas City). You will then have a like new operable camera that you will love. As noted, the back with the lever IS the one with the most enjoyment and can be very hard to find. Call Clarence, see how soon he can get you in (I pray he is still in business), then buy this camera. The photos one can get from one of these with a little time, a tripod and an eye for a picture can be spectacular.
I'm not sure if that was directed at me but I've actually already got a Super 23 in near mint condition. I'm just looking for some replacement parts (ie the grip)
