Self Bailer for dinghy or canoe

A PT 11 builder wrote to ask if I know of

...any rower/kayaker/dinghy sailor who might be interested in a pair of auto-bailers. I bought them for my Penguin racing dinghy about 60 years ago and never installed them, so they are still like new, with instructions, installation templates, and mounting fasteners as purchased. Here is a link to photos:
Mine were branded "Falcon." Almost exactly the same item is sold by various marine stores, branded "Anderson," for ~$60 to $80 each today. I would like to be paid $60 for my pair, or best offer.
