When I bought a second hand Ridgeback 501 in about '86/'87, my mate got a Saracen Tufftrax which looked quite similar in shape and stem set-up to this. (except his was JCB yellow)
I have browsed the 1996 and 1997 broshures and I can only find so far tehy are called Jushua. But the bike is not in the 96 and 97 I'll see if I have more from GF.
