I've got a beautiful Zeiss Ikon Super Ikonta 533/16 that has Tessar Disease and could also use a good CLA (otherwise, externally, it looks like it was bought new and put in a drawer for ~60 years). Every time I think I'm going to spend a lot of money to get Jurgen to fix it, I get another camera or something (this time it was a Yashica T4... can you blame me?) It's such a gorgeous folder, though. I really have to put some $$ aside and get it into Jurgen's capable hands.
