This is an original 1932-33 Cadillac Delco-Remy Distributor 662-Y for V8 engine.  Pretty nice condition, has been rebuilt, but not sure how long ago-see photos.  This came out of an older parts dealer that recently closed up and sold out.  I do Not have the cap.  Delco Book shows this fits 1932 Cadillac V8 355-B, 1933 Cadillac V8 355-C, 1932 LaSalle V8 345-B and 1933 LaSalle V8 345-C.  Please check my other listings.
