We’ve recently added this wonderful electronic flash unit to our collection. Many of the lesser known accessories from Yashica often go unnoticed and become a bit mysterious.
We were lucky to find an almost complete set from around 1962 or so (could be earlier). I believe we’re only missing the instruction booklet and a few minor (but desirable) plastic bags. The box and styrofoam inserts are in excellent condition. The flash works perfectly and more than likely is unused (as is often the case). Image number 3 is from a Japanese Yashica-Mat EM instruction booklet. There are some differences between ours and the one pictured. One has a coiled cord vice a straight cord and the attachment bar and knobs are black vice silver with gray knobs on ours.
