A very early Brass Carburetor made by the Zenith Carburetor Company for I believe an antique motorcycle or small stationary gas engine. Carburetor is a smaller carburetor and seems to be in good loose condition. Bolt holes are in a 2 in center to center with a 3/4 in opening. What I have in the pictures is what I have, no cracks breaks or welds. Everything on carburetor is loose. A very nice looking early Patent applied for motorcycle carburetor. This would make a great carb if one was building a model tractor or fixing a antique motorcycle. May also fit a Koehler hit and miss gas engine. Please see pictures for more information and condition.
