This is a very hard to find original Schebler updraft brass carburetor for an early horseless carriage, car, truck, or other engine.  Please do your homework to be sure it fits your application.  It is nearly all brass and seems to be in good, used condition with no cracks, breaks, or repairs of any kind that I can see or know of.    Everything moves as it should.  The choke shaft seems to have almost no wear.  The throttle shaft has very minimal wear.  It mounts with two holes 2 1/2 inches apart on center.  The intake hole is 1 inch in diameter and the hole where it mounts is 1 1/2 inches in diameter.  These original early Schebler brass carburetors are exceedingly tough to find in the wild or even at swap meets so if you've been looking for one for an authentic restoration here's a very nice one.  Let the pictures be your guide.  I can always be reached at 262 573 193 1 if you'd like to talk about it.  Good Luck.
