I have had a studio for 30 years. Over the years various people have offered me equipment. One that stands out was a lady I knew that had a Leica IIIg, with various accessories, in mint condition. She wanted a modern (for that time) 35mm SLR. I traded her (ordered brand new) something like a Canon AE-1 with lens. She was very happy. Of course the IIIg was worth about triple (or more) what the Canon was worth. Alas when I got into a financial pinch I sold it. Never again will I sell photo rare gear. I still have plenty of Leica gear for my use, but I have never since had a IIIg.
