This is a 2-blade, brass propeller, by Michigan, # AJC120 (I'm pretty sure that this number is correct). I'm not sure what dimensions are needed so I'll give as many as I can. The height at center hub is 4 tall.
Housing at bottom is 3 3/8 O. Rod going through, with 2 keyways, is 1 1/4 O. Hope my pictures will give you more info, if needed.
Most items will be sent First Class or Parcel Select, according to weight.....
