An accessory carburetor question

[Dliepelt]

When I was a kid, my dad bought several boxes of carbs from a long time family friend. Dad had no interest in the accessory ones. He never looked at them. When I would come home to CT from college, or from MI, I would go thru that box every time. I remember there being a few Stombergs, a few Zeniths, an Air Friction, a Griffin, some others.

Then a kid dad was friends with rented Grandpas house. The kid stole tons of T stuff (new Stipe cams, a Laurel cross drive, 2 rebuilt DU4's, heads, A dash panels), and that box of carbs and sold it on ebay. It makes me madder yet that dad doesnt even believe me that the box even existed at all. But that doesnt matter now.

There was one carb in the box I never saw before or after. Dont know who made it. I assume it was aluminum, instead of zinc, because it was in good shape. As I remember it was sorta the basic shape of an NH but a bit smaller, throttle and choke plates the same places, but the mixture adjustment was a T shaped piece that the normal adjusting rod fit into, but it had about a 1/4" bleed hole in the side. The only mixture adjustment was turning that T shaped piece which moved one hole past the other. 1/4 turn was all it went. Dont remember that there was a name on it at all.

Does anyone recognize what it mite have been?
