While there was speedway here in the 60's, it wasn't really organized, so I don't know if there was much in the way of decent sponsorship. The first official US National Championship (since 1948) was won by Steve Bast in 1969 (although some sources state that Rick Woods was 1968 National Champion).
The problem is that while there are photos available online, it is actually difficult to pinpoint the years in US speedway.
While the leathers tended to be coloured, I really don't think there was that much in the way of sponsors' names. I will look into the Basts, and people like that.
I know exactly who you mean at Rye! I hadn't gone through all the NL teams yet... Still trying to figure out the one at 'Boro.
EDIT - Got him! It wasn't five consecutive years, that's what screwed me.
I've found several that came up a year short, either just having a four-year British career, or like Zenon Plech, just having one year somewhere else...
Not just YOUR opinion. Vaculik should finish Top 6. Despite all the negative Nancies on here, Doyle has clearly proven himself one of the top boys still, and I would be surprised if he didn't finish Top 6. Likewise, I'm convinced that Holder would have finished Top 6 were it not for his injury, so there's another automatic choice.
It's a good thing Ray Harris, Jim Tebby, Norman Strachan, and Eric Boothroyd arent riding now...
You never complained when it was at Coventry! OR when the BLRC gave PC an unfair advantage every year!
