Well-used, but working Nikon F-36 motor drive... $75.00
Doesn't come with a battery pack, but works fine. Just got one that's a bit less cosmetically challenged to replace it, though. Buyer will need to source a motor drive plate for their F body and possibly will need to have their camera synched to the drive. I got lucky, in that my F happened to work perfectly with the drive without any service being done to it.
$75.00, plus shipping via USPS Priority Mail. US buyers only. PayPal is accepted as a personal payment or gift. Also, USPS Money Orders are fine.
