For Sale Praktica FX Flash Adapter or ?

I think this is an adapter for the Praktika FX SLR to adapt it's sort of strange two pin flash arrangement (X or B) to the now standard PC flash sync type connector. The pins that mate to the FX body are spaced by about 0.4" and are about 0.075" in diameter. If anyone is familiar with this connector, your comments are welcome! These are obviously uncommon today.

Made in Germany.

Price: $15 plus shipping

I just picked up an FX, so I'd be interested. The pin spacing seems about right.
