The fork is an interesting piece. It is by Showa of Japan and it is in fact identical to the fork Tioga carried in their line up.
The fork also came in the 1993 and 1994 full suspension Miyatas and Koga Miyatas, labelled 'Miyata'.
I thought there was a review on it in Gallery 2 manufacture section, but there isn't. I recall it is very decent functioning fork, with a small remark on that it is not stiffest.
