I have no idea what that spring looks like, but you might be able to make your own if you can find a source for spring steel. A search on the net for spring steel would probably get you some where. Otherwise, just order it from Mamiya. If nothing else, you might contact Oshkosh Coil Spring in Oshkosh, Wisconsin and they can tell you where to buy that stuff. They are only a 100 miles north of you. Ric.
