Would be gear substituters,

If I remember correctly, Tom Marcotte had a number of them made some  
years ago.  If that's right, he would have the specifications.  You'd  
want to know:

Number of teeth/pitch/pitch diameter
shape of teeth
thickness of gear
offset of rim from center area
Diameter of hole and nature of flat in hole (the center hole is D  
shaped, or possibly has two flats)
Material of gear (maybe stainless in originals)
