This is a Marvel Schebler Carburetor.  It can be used on any Model A Ford from 1928-1931.  A lot of Model A guys like to run these Carburetors on their A's.  This came in a box of parts I purchased.  It appears to be in good condition.  The choke and throttle levers move freely.  The threads are good.  I lightly bead blasted the Carburetor.  The (12) pictures show the condition of the Carburetor very well.   If you have any questions or need more pics just send me an email.  I always leave feedback after feedback has been left for me.  Insurance is the responsibility of the buyer.
