Those T2s are puzzling me... I have two pairs and neither have that soft, sculpted crown (noticeably on the back) - more of an agricultural PACE-like design. Would these here have been OEM versions for Kona (subsequently recalled)?
Are yours both 1990 with spatter paint? The only one I've seen similar to this is on the 1990 Explosif shown below, once owned by Hilts. I have no photo of a Track Two on a bike later than 1990 before seeing this latest one.
It begins to seem clear that although this bike is NOS, it is a bitsa built up by the shop from a 1992 Explosif Pro frame and other suitable parts they had to hand.
The fork may have been difficult to sell if there were known problems with them, but I wonder if the problems were exaggerated? There are lots of 1990 Explosifs still running around with intact Track Twos. I have more photos of 1990 Explosifs than of 91s for example, and I have only one photo of a 1990 Explosif with any fork other than a Track Two. Maybe the problems were just with one particular batch perhaps?
