Without 1996 to look at, assuming 1995 it should be easy to determine if you know what rear end you have (other than hunting for butted tubes*) and unfortunately I don't know what the G model is for (unless you find someone that does have one)
Manitou Comp = Nail Trail FRS
Manitou M4 = Team FRS.
If you still have where the top sticker, where the name went, even the shadow/outline, it may also give a clue.
Would need to see pictures of 1996 one's really. (EDIT, Not a 1996 as different rear sus.)
Team FRS 1995 had a butted headtube. Though internal or external I don't know as cannot see from the pictures In the catalogue. Cannot even see if the 1995 had the reinforcement rings.
