Who made these slides?
 

Any idea who made this slide valve intake?
I think I know who designed it but he says he lost control of the plans and a third party knocked out a couple sets.
I saw a set on an EBay engine for sale this week but the owner doesn't know who commissioned them.
Any information would be helpful.

I thought of Protechnik, but some pics that turned up in a search look different than these.

Possibly one offs? Looks like these Fabworz ones that I found the CAD of.

The cad renderings looks correct. We know they aren't one off because I have one set and Euro Parts West just sold an engine with a matching set.

Well anyone could have made a set with the publicly available CAD.

Same guy was making some barrel throttles 5 years ago according to his Instagram. Probably worth an email Aaron@fabworkz.com.

Farr Yacht Design follows his Instagram and they are legit as it gets in the monohull racing yacht world so he must be a pretty legit small engineer/manufacturing shop.

Aaron Hatz?

If Fred Apgar was still around, he'd be able to ID them.....

These are (unfinished) Protechnik ITBs. Like stownsen914 said, not a match to Henry's photo.
