I have a box of about 1000 35mm slides and it simply vanish. I have tried for 15 years to find them but couldn't find them. I know they were not stolen. Too bad too because they were the good ones that I have selected to keep and I lost them while that bad ones are still laying around the house.
A few years ago I went stupid buying up a buttload of P&S cams. Quite a few of them seem to have vanished, though I found them again last night, in a plastic bag hanging on a nail in my basement where I wouldn't lose them.
Nothing really expensive, but I had a Nikon Lite Touch AF 28mm f3.5 compact disappear that I wished I had back.
I got it free and love it, haven't found anything similar. I've though about a WTB on here or trade, I've got a few pre-AI Nikkors I would part with in a trade for one. I loved it, was a great 35mm compact walkaround when I didn't feel like carrying an SLR. I could literally fit it in my pocket.
I live in a small townhouse. When I moved in I brought an LPL 6x7 enlarger WITH transformer. I want to sell/give the enlarger but do you think I can find the transformer? It's the size and weight of a house brick for heavens sake!
