Fan part needed

[tonyabacus]

Not sure if I am posting in the correct place, if not then please let me know where it should go.

1970 Elan S4 Coupe
I want to put an original Lotus cooling fan on the front of the radiator, however despite having the motor and the frame I cannot for the life of me remember where the actual fan blade is, a number of house moves and a failing memory don't help. So before I start digging up the garden, being the only place I've not looked so far, does anyone have a spare one they wish to sell or donate! It is only the plastic fan that I am missing.
Thanks
Tony
