I have had 2 of these for 30 years or so and have never used them. It is unlikely I will ever use them so its time to consider finding a new home for them. It seems like they would be really useful for plate photography but I may be mistaken, I know they can handle thousands of watt seconds of strobe light, but finding info on them has been difficult.

Any help or info you all may have would be great, thanks.

The second photo is just for color and the ring shown is the flash tube.
