For Sale FS: GX680 polaroid back (model I, compatible w/ I,II & III/IIIS bodies)

Selling a spare I won't be needing.
Has definite signs of wear, but works fine and rollers are clean.
Darkslide has slight curvature to it, but when inserted in back, is completely light-tight that I've experienced.
Works fine on my GX680III body, so I assume this will be fine on the I & II models as well.

See pictures for wear marks/condition.
