I may be able to help, I have two pairs of GT forks, both very similar looking. Have a look at these on this old post. viewtopic.php?f=2&t=106978
First, the heavy one, they are cromo and weigh 1092g. The steerer is 11/8” and 190mm long. These have a 2000 stamp on them. I have removed the mudguard eyes from these.
Second are much lighter, 875g again with a 190mm steerer. These have a 93 stamped on them and I believe they came from a Zaskar. Mudguard eyes are still in place.
Both have been sprayed with rattle cans.
Looking for £15 for the heavy ones and £25 for the lightweight ones, unfortunately if they require posting, that will be extra.
Please let me know if you are interested.
