Yes - Berg was sponsored by Strata. I guess it was a Canadian company and I have a feeling they may have still been with him when he broke into F1 with Osella about 1987.
Berg looked good out here in Atlantics in January 1983 and so I expected good things when I turned up for the opening round of the British F3 Championship in early March - but there were a couple of guys called Senna and Brundle who looked handy while in any other year, Davy Jones would have shone.
