Can't help with the reggies (my anorak had self distructed by then, but still maintain a distant interest and a long memory for some stuff) but that "Zero" strikes a chord... is it French from the Salis collection? Certainly not UK I'd suggest...
One of the serious spotter mags has a good on-line airshows listing. Not complete but better for the more recent years. I'll try to remember which one... You tried googling?
