Sold Sunpak 522 Thyristor

I purchased this a few years ago from a local camera store that was going out of business, it looks like it's never been used. It was missing the battery holder but I found one on Ebay.
Includes the camera mounting bracket and the sync cord. I think I have used it perhaps three times in all. It's really nice, but flash photography is not my strong point.
Just tested it with some batteries, works great.

$50 dollars includes shipping in the U.S.

I have one of these - it rocks! Great flash and a good price too.

I tried mounting one to a 4x5 Crown Graphic with the flash holders but the ring was too small. Anyone adapted this to a Crown side bracket?

Bump.
