I've been reading the discussion of Cokes on a 28 and I know the rule, never say never. How confident can you be saying 29's and 57's always came with cokes? Has anyone ever lettered a 29 or 57 in the coke time frame with the regular targets not as checkered Goncalo Alves target grips? I've always thought 29 & 57 cokes and 27 & 28 regular targets. Thanks
