I did a quick facebook group search on these shortly after I bought it (trying to justify another bike), Someone on there had posted a few threads or commented on threads about them, so I reached out and asked, turns out it was DeeEight, that's who I heard the Dekerf reference from.I think there have been Team Compe crop up with Ixxx numbers.
They also crop up in Germany.
Best bet is get on the Canadian Facebook group and hope someone happens to be reading it that worked at Rocky and would have welded up these frames at the time.
The none Ixx number would say made/farmed out by them, but one poster who I think new his stuff said they where not.
(probably in those links, long time since I read them) DeeEight was around at that time and tends to know his stuff and you could probably get some info from the old Newsgroups, often a good read.
I may well be wrong, it been a while.
