after a little bit of googlestalking I ended up finding this company description

http://www.whorunsit.org/companies/02170756

the report says it was active between September 30th, 1987 and October 5th, 1993 with some interesting name changes in between

what's interesting is that K2 Plant Hire is still active with both Bill and Jimmy enlisted as "musicians"
