Hi Blackwidow#2,
It was Green.
I checked here and was trying to match up which of the 8 it is.

but no green ones.
Then I found this - it was up for sale in 2007 - that would have been somewhere around when saw it. Looks like it is number 5 and must have originally been Black (and says 1990 model, not 1991)
