My Xmas present from a bestie has been brilliant, as I've some good bits for my archive in the stack of magazines he sent me. It's helped plug some gaping holes, and proved that the deductions I've made from incomplete info were (mostly) surprisingly accurate. But it's also sent me on a chase for new information, because I'm now armed with some concrete dates from 1984 and a fixture list for 1985.
The sticking point has been (and always will be) that short oval racing is not nearly as well documented as circuit racing, so this part is far easier said than done...
