Triangle HEG history

Today I examined an older bullseye pistol that had a full length Triangle rib with a tall under cut patridge front sight. I've seen several Triangle rear sights over the years but never a rib. Can anyone enlighten me on the history of Triangle and what the HEG stands for?

Herman Elliason Gano, I believe.  Anyone?

Greetings,

Not sure about Herman; but, Elliason and Gano seem correct.

Gano was also instrumental in the development of the 38 AMU in the late 50's and 60's.

Cheers,

So what is a HEG rest? Anyone have a picture?

The photos are reportedly a modified HEG used by the AMU.

Of the Herman-Elliason-Gano I'm only familiar with George Elliason. Who were the other 2?

AKA THE BEAST

Neat! Do you have a picture with a pistol in it? 
How is it used?

Thanks

No photos of it with a pistol.  I got those photos from a Navy buddy who visited the AMU.

I saw somewhere it was Hebard.

Doing some research and some internet digging.....
HEG were the intials of Hancock-Elliason-Gano who developed the (above) pictured rest.
Herman D "Bill" Gano was a master armorer with the USAAMU. He passed away in Alabama in 2015 at the age of 86.
I can't find anything on Hancock.
George Elliason as most know developed the "Elliason" rear sight and was a noted gunsmith who had a shop in Detroit Michigan. He worked for Colt for a short period of time in the early 60's in the R&D department. He moved to Texas in the later 60's. I can only find 1 death listing for the surname of Elliason, George who passed away in 1976 at the age of 85 in North Carolina so I'm not sure if that's the right person.
Can anyone else add to the story?

A little more gleened from the web. I can't substantiate the information. There's very little information out there.
Triangle either did not patent their sight(s) or let their patent expire. Bo-Mar started producing their similar sight and patented it which effectively ended Triangle. Can anyone add to the story?

The pistol is set into the well shown in the second picture, with the trigger guard resting on the insert.  The front of the grip is aligned against the closer part of the well in the picture.  The fasteners are all tightened to the recommended torques.

The bottom, at rest, sits against the adjustment shown at the base in picture one.  When the pistol fires, it recoils against the long spring shown in picture three and the spring returns the rest to the point against the lower adjustment referenced earlier.
