Are you looking for a particular period, as I notice what you have there is largely '92 and before ?
IMHO, '93 onward things got a bit different and with that I believe '92 to be the best year in my mind.
Mind I saw I think it was a '91 tufftrax recently in the town up on top of a wall chained to a fence, well battered it was, but still in use judging by the effort the owner had gone to to stop it being messed with, the bottom of the wheels were at shoulder height ! A sort of reddish orangey colour. Mind that old Saracen I sorted for my pal last year was a '91 tufftrax elite, yellow with 200gs on it, I replaced with Altus A10 I had going spare, but it was rusting badly and really nothing to write home about except for perhaps the internally routed rear brake cable.
There is a '92 tufftrax up on ebay at the moment, the grey LX liveried machine in rather a poor shape, but odd I thought as the cycle has the tange suspension fork of '93, perhaps it was one of Saracen's cross over models.
Just taken delivery of this beauty.....always wanted one and now I have one! Tis a 91 Traverse Hydrotech and is pretty mint. The chap i bought if from included the original bars, seat post & stem.....which is far too long for my back!
