That is evidently some type of Carter carburetor tool. That is how Carter puts there name on their carbs.
No PHuscher...NO one can Pull the venturies from a Carter carburetor, nor most Holleys. You can machine them out, you can use a hammer and chisel to beat them into submission, you can use a hand grinder to grind them out... They are a cast in part..!! That tool will not pull the booster venturies out either. I actually doubt it's a "carburetor" tool at all. Mike
What is the distance between the 2 dowel pins? Maybe they line up with the single barrel mounting holes on the inlet manifold.?
This image and the corresponding part number are on the website that @carbking has for his business. It is identified as a venturi puller.
The tool is a venturi puller for the early Carter brass bowl carburetors. The pins in the end of the tool are inserted in the flange mounting holes. The screw (long center piece with the grooved end is screwed through the venturi. The retainer is inserted through the air intake into the groove with the chamfer toward the flared end (bottom) of the venturi. The large ring with the hole is then screwed up, pulling the retainer in its groove, and with it, the venturi. The original tool was numbered 15200. After Carter renumbered most of their products with a "prefix-suffix" numbering system, tools were given the prefix "T109". The part number assigned to the venturi puller was 100, thus the same tool (renumbered) was part number T109-100. Yours is the original 15200. Pretty rare, but demand is also pretty rare. Very few carburetor rebuilders still rebuild the brass bowl Carters (discontined after the 1932 model year), and all of which I am aware already have a venturi puller (or a couple). If you collect carburetor tools, pretty cool tool. EDIT: service instructions, with a cut-away of the carburetor: http://www.thecarburetorshop.com/Service_Carter_Brass_Bowl_updraft.pdf Jon.
