According to the TRF  TR 6 parts manual the TR 6 came with three, possibly
four different fans;

     1) Part # 211986 - 6 blade metal fan  (questionable if ever fitted)
     2) Part # 311868 - 7 blades,  yellow plastic, fitted to engine
CC75000.
     3) Part # 308353 - 8 blade, yellow plastic, alternative to #311868.
     4) Part # 312301 - 13 blade, red plastic, fitted after engine CC7500.

The 13 blade fan, Part # 312301, also required an adapter, Part # 157876 to
be mounted on the crank extension.

I would imagine that the 6 bladed medal fan mentioned above is the same
tropical fan for the TR 4As. If that is true
any TR 6 fan should fit a TR 4 as long as the appropriate mounting hardware
is used.
