Like Poppy there was about 4 or so I couldn't name. I don't recall the 1998 home kit either. At the time I was a steward at the ground & my posting was on reception, so I never got to see them play at all that year. As I recall it was one of our worst seasons & everyone was beating that year. So I was glad I didn't see any games. It was a nice kit though & I'd like to see something similar in future years.
We only played half of a season in that kit from 1998, the last part was played in the red away shirt (with the big viking image on the front).
That same red kit was still being used in the 2001 season.
On the subject of using the same kits years later, Our 1996 all blue away shirt was worn in the 1999 play-off defeat at Dewsbury Rams, coincidently, we never won a single game in that blue kit.
