Anyone recognize this carburetor?

Cleaning up my shop and found this. The manifold fits a T block and I think is from a vaporizer. A straight bore venturi.

Zenith. Period correct T replacement carb. The bowl cover plate had the name & other lettering all over the top. I see its been replaced with a home cut cover. Bolts on a stock manifold. Not normally seen on a vaporizer manifold.
The venturi is pot metal & most are exploding. I have made a few venturi's for the 2 I have restored. Havent tried to run one yet, but, it is a promising looking replacement carb.

The adapter from the carb to the manifold is cast iron.
So unlikely that it was a “one off”.
I thought it was interesting at least.

Interesting adapter to get a stock pattern to a vaporizer.
Another interesting thing about the carb is the long & short throttle linkage positions for fitting both early & late carb applications.

John's correct
Zenith made some wonderful carbs...some for Model T and some that can be made to work on a Model T. That particular carb is significantly lacking in any sophistication which would warrant restoration for the sake of any kind of performance. For curiosity or interest's sake? Sure. Performance? No.

So probably the best part of what I have is the adapter piece!! Certainly gives me something to work with!

Those are good carbs. I ran one on the 1915 and it increased the power and speed to a startling degree.
But it had a few drawbacks: It had a flat spot I could not get rid of, making it easy to stall when taking off from a stop. It idled GREAT and it was very much faster than the Holley NH it replaced, but getting through the transition from "idle" to "fast" was frustrating. Second, with the extra power (and it really had a lot with the Zenith), it made the car overheat. Third, the pot metal venturi, though intact, was crazing with age.
