Nikon SF-200(S) 35mm slide feeder for CoolScan film scanners. I had this with a CoolScan 4000 ED. As with that listing, no reason to believe it doesn't work as it turns on just fine when plugged into a scanner, but it has been in storage a long time and I don't have film or FireWire to test this stuff with. Listed AS-IS, FOR PARTS, UNTESTED and priced accordingly.

Let me know if you have any questions!
