To throw my hat into the ring, I have a freezer full of film at my studio which includes a box of misfits: a roll or two left over from projects and jobs past. This is a ridiculous pastiche of emulsions, including some really cool stuff. I don't have a list at my fingertips here at home, but just off the top of my head I know I have some Agfa Ultra 50 and Ultra 100; some Konica SRG 3200 (yes, 3200 speed color neg, though it's really more like 1200 speed...); Fuji NHG II 800, a whole brick of OLD Kodak Ektachrome, some Fuji Velvia, Astia, and I don't even know what else. Some of this stuff is really old, but it's all been frozen for years.
So the first three respondents will get a grab bag of three- let's make it five!- rolls of 120 color film; your choice of E6, C41, a mix or a surprise. I'll choose the speeds and emulsions you'll get, unless you really want something specific from what I've listed- but if you do ask for specifics, just take one roll of any given stock. PM me. This is fun!
