QUESTION: ENYA or OS

Several years ago, I acquired a H.29R U-Control engine designed for team racing and ported somewhat similar to the Dooling .29. It became available just prior to the Schneurle ported engines and, apparently, was discontinued in favor of the Schneurles. Therefore, a couple of questions.
1. Was the engine OS or ENYA? I think it was OS but not certain
2. Are any still around?

I'm not very familiar with Enya, but OS built a series of engines that they marked Max H at about this time. The Max H 35 was a ball bearing, baffled piston engine that was aimed at combat. There were several versions of the Max H 40 including a 40P timed for R/C pylon racing. My guess from the H marking, is that this was an OS.

I was looking for something else in the back pages and came across your post.
Does it look like this?If so,it's definitely O.S. They're very nice,about the same power as a good Dooling or Modded McCoy.As you observed, they are basically racing engines.As usual with O.S.,very nicely made.
