Would love to know who that person was, and what his thought processes were.

Very interesting. I would LOVE it to be in my collection.

I too wondered what the thought processes were, not just for the three ring piston but the perforated one too.

You might not have one made by whoever made the one pictured in this thread ( maybe one person made a few maybe a few people have made them as the drawing is out there) but its eminently doable if you have a lathe & want one.
