a basic sekonic light meter. wasn't lost though or misplaced but "borrowed". it seemed to be "invisible" for about a year and wasn't in my camera bag, where it had lived for 20 years ( but it was ) ... it showed up again about a year later after I bought a replacement (L something ) and put it where I usually put the "other one" ... it appeared again, together with exposed film that I never bought, stored, exposed and have no idea where the photographs were from. I sold the replacement meter to someone and still use the original seKonic purchased years before. the film is probably in a print file in a pile of other negatives from that time period when they were processed. since then and before then I haven't lost a thing...
