Here is a vintage yashica-mat copal-mxv 80mm with leather Case and extra lens , this is a used item but all the nobs and buttons seemed to b functioning, as seen in the pictures one bottom of the leather Case the stiching has become lose (this could b fixed easily with a little leather glue I believe.) A small bit of like build up or corrosion Round edge of a small front knob ( see in pics) I didn't try and clean may come right off. Overall for age looks very good and  seems to function smoothly. This is a used item. Thanku for veiwing and greatly appreciated.
