I have specialized in the PHOTO  field since 1968 holding  an A.A.S. degree in Photographic Technology from the SUNY - Farmingdale, L.I., NY and check my items out carefully, before listing. I also hold degrees in Earth Science  B.S. & Geo-Physics M.S. & Electronics B.S., and taught electronics for 26 years, so you can be sure I check these items out. I have been known to rebuild shutters of Leaf design and work on T.L.R. & folding Japanese WW2 cameras. In 35mm , it has too be economically feasible before I will rebuild these days as many 35mm cameras are  impracticable to repair as they sell for little money on eBay. Often I clean lenses as my business is centered around sale of LEGACY lenses for the Mirror-less cameras, where they perform far superior than the horrible rangefinders of yesteryear they were attached too! 

 I use PayPal as my #1 way to be paid fast, and ship fast when you pay fast. Domestic Priority mail is 1 Business Days from the post office under best circumstances.  I have a 1 day BUSINESS DAYS  turnaround in sales in house, from the time YOU pay and I RECEIVE  the money, not when you sent it, weekends excluded of course! . So together it could be 3 days before you receive your item at times. Please be patient and professional and trusting. Holiday periods the USA post office is very, very slow, DO NOT hold me responsible for HOLIDAYS  in the USA, please; or snow storm's in the NE. of Pa. where I live! Regards, Don
