Les,
Yes, my D80 still has the metal fan.
As to my grandparents' 1985 Heritage II, no, but it is the similar 11-blade gray Lexan fan.
I saw all your Super-Sweep disassembly pictures and, I noticed the armature is exactly the same one used on the D80 (part number 114967), while the field coil was unique to your machine (part number 103977). Bearing plate is exactly the same, too.
