It has the raised lettering " The SCHEBLER INDIAN APOLIS IND" the number stamped into side of bowl seems to be 10311 . The last digit is a bit fuzzy. The brass is smooth . My great grandfather had it as a spare for a Fairbanks morse . Banged around for a long time in my late father tool box. Are parts are free working and original. Wondering how rare it is and what it's worth? Thanks Paul
Looks to be in good condition but missing the float valve cover From the pic I am guessing 1 inch or 1 and a quarter inch. Size is by the pipe thread where it mounted to the engine. I have about a dozen 1 and a quarter ones for sale between 75 and 150 I have 3 ro 4 1 inch that are rebuilt to be compatible with todays gas. they are 225 Hope this helps Ernie
