1 of about 170 produced with Merlin titanium lugs.
Full black XT 730 except cranks, like Ned rode it but witch black IRD post and black Specialized stem/handlebar combination as shown in the 1991 catalogue.
So yours is full XT? Interesting.
I think the 91 catalog has it as a full Suntour XC Pro bike, though you're right about Neds (from the 90 Worlds anyway). Though Ned's bar/stem combo was Litespeed.
Mine is all original as well (so far as I can tell)...but with the full M900 XTR build which wasn't until 1992. Not sure what happened there.
