I have a set of 99 boxxer 151's in red. I bought them of rob kitchin when he was riding for team animal - they are in good working order but have a few slight issues.
The drop crown is in grey and the part bolt that attaches to the steerer tube is threaded but I'm certain I have the original red flat crown somewhere.
The axle is missing the end cap - has been missing for years but i always just put the axle in and tightened the pinch bolts. The threads inside the axle are damaged so a new end cap wouldn't fit.
I took them to Les arcs last summer and the seals at the top of the lower legs have clearly gone as oil was coming out the top between the legs and stanction so these would need to be replaced as well as the oil.
Other than that they have performed perfectly in the 12 years I have owned them and done me proud - only selling as I cracked my GT Dhi and therefore am not using them.
If you are interested give me your email address and I'll send photos
