For Sale FS: Generic Winder for Nikon, cheap

I bought this in a lot of camera stuff in a local auction. It's labeled "model N-2 Electronic Power Winder for Nikon - Made in Hong Kong". It takes 4 AA batteries and appears to be in ok condition. But, I don't have a camera body to test it with, and I have no definitive information on what cameras it would work with.
I can make detailed measurements if that would help.
$5.00 USD + postage to anywhere, with kickback to APUG.

I have one of these and I believe it works with the FE2 and FM2n but not FE or FM.

Ken, would you like another one?

OK everybody, free for the postage cost.
