A co worker yesterday, Brings to work a ikoflex tlr and a Black leica IId serial 73828. He tell me he believe's there worth a forture because these cameras appear worn and were kept by family for many years. So he kept them on a shelve for all to see at his home. The lens is frozen and the optics are covered with haize. The shutter still works, very sluggish. The covering is coming off the body. Only a couple of small scratches on the metal. I would like to talk him out of it If I knew how. What do you think would be a good offer on somthing like this. This camera has a plug in the back of the body and , an 0 engraved on the lens mount. I don't the the haize canbe cleaned. This lens is uncoated f3.5 to f18. I don't have books on value, what would be a good offer.
