Vintage Mardaves wanted

Extremely keen to find any owners of very early Vintage Mardaves, ideally someone looking to sell but if not would still be very interested in sharing information / photos on these very rare cars?

Matra Simca
Alfa
Lotus 72
Lola 280

These cars were released between 1970 - 1975 with some sold in small numbers, could someone have a relative who raced one years ago and packed it away? Would love to hear of any in existence!
