Here is a functional but slightly ugly Canon Winder FN for the last F-1 model (the one with the hot shoe on the prism). It's got only mild brassing, works great, no battery corrosion... but there is a chunk missing from the base below the grip. And whoever owned it before me built that area back up using gaffer's tape! (Hey at least it's black, unlike duct tape...) I run the bigger AE Motor FN on my cameras, so I have no need for this (it came with a body I bought.) So how about $20 plus $10 shipping anywhere in the world? If it's going outside the US I'm going to remove the 4 AA batteries to save weight, but within the US I'll throw those in - brand new, just used to test the winder.
