Yes. All early Tamiya TRF211x's.
Quite a few were made, team drivers also modded away happily to their own cars.
Made up of Astute/Madcap/Super Astute & prototype Dynastorm parts, a few with custom made parts or adapted parts from other cars, like the lower right hand corner one. Popular mod was RC10 gearboxes grafted on, as the Super Asute gearbox & diff & slipper was never really any good.
Do you want to sell ? If so, im buying...
