Brilliant! Thanks for sharing. This week we've had new additions to all of the Kona SN lists apart from the Caldera list...so here's hoping
These are excellent pictures as well, all of the specific identifiers are clearly shown that make it a 1991 model and not a 1990 or 1992. #153 sounds well into production but from our lists perspective, this is an early one. We only have 10 on records that are earlier.
TET 153 - 19" 1991 Black - Integral Welded Seat Post Clamp, Triangle cut-out Dropout. Seat-stay U-brake mounts.
I'll see if I can find out more about who that rider might have been.
