This camera came from a local auction house last year - one of a dozen or so cameras, all rather battered, in one lot. The top plate and filter ring of the Petri were both badly dented, so I waited until I could buy a parts camera, to do a repair. Unfortunately, what I bought was a Petri 7 - which has a different top plate. I fitted the rangefinder from the 7 to the 7s (the 7s rangefinder was missing parts). I was able to straighten out the top plate, and improve the filter ring. Oddly enough, the shutter on the 7s works accurately on all speeds, and the selenium meter works fine. All that was left to do, was to adjust the rangefinder. I did this on the footpath outside my house, aiming the camera at a house at the end of the street. The view through the viewfinder. I used the chimney of the white house as a target. The Petri doesn't have anything as wussy as adjustment screws - you have to bend the bracket carrying one of the rangefinder mirrors - the one with the holes, here: The bracket was bent using the pliers shown, until we had an accurate overlap of images, with the lens at infinity. Petri had a special tool for making this adjustment.

Scary! I would have ended with a pile of broken glass and metal...
