Re:
I've got a Diamondback axis TT in that size (well smaller than my 19 inch one). Bought as a project to see if I preferred the smaller frame, but I've decided I like the larger frame so I've done nothing with it. It's very tidy but does have a couple of issues:
Rear canti brace has been removed from the frame. I was going to run V brakes so not an issue for me. I was going to tidy it up a bit but it's not a bad job, or enigma can weld on a new one.
One of the rear brake mounts is broken. Another job I was going to get round to if I kept it. Easy out and a replacement will solve this (I may have a replacement in the spares box).
It doesn't have any decals on, but I do have a nos set from 93 (I think the frame is 95 due to snake stays), or gil_m has some on file for reproduction.
Let me know if it's of interest.
