I picked up a polaroid mp4 with the rail and no baseboard or lights. It all seems to be in pretty good shape, the shutter is a little finicky below 30. (Any quick fixes on this it is a copal shutter with a tominon lens.) Can anyone tell me what I actually have here? What is it worth? Is there anything fun I can do with it, or would it be best to just put it up on ebay?
