Another prototype TRF, from Tamiya. This 4WD TRF was developed at the same time as the TRF211X Prototype, and displayed at an Tamiya expo some time in 1992.
This prototype was allegedly produced in very low numbers, 100 kits is a "guestimate". TRF did not return with a 4WD buggy until the 49401 TRF501X was released in 2006.
All parts according to Tamiya Guide books, Tamiya manuals and Tamiya parts listings.
