I have an aluminum propset from AQ280 diesel application.
so they should be A series and the rear prop is 4 blade so that agrees.

Only legible numbers are

M24431
R5795 (4 blade)

M18274
R5793 (3 blade)

can anyone cross those? or recognize the numbering system? I thought Michigan Wheel with the m numbers but I cant figure out their site anymore...
