This is a Minolta Compact Bellows Unit. Both the body side and the lens side are Minolta SR mount. When folded, the bellows are stored, and the body, which has a structure without rails, is compact as the product name suggests. I believe there are no defects that would hinder use. Since it is not unused, there are some scratches and scuffs. There is a part of the metal part of the sash that has discolored to brown, possibly rust. Please check the images and consider purchasing.
