I got these cantilevers from a good friend and excellent bike mechanic who said he found them in the stock room of a bike shop that was going under and was bought out by his shop.

Anyone seen these before?

They are extremely primitive, having no spring adjustment....I guess moving the spring around and physically twisting it are the only options for centering.

That said, I might use them. The machining of the arms is really neat.
