Buyers were (and still are) free to special order any combination of sizes they wanted as an outfit so just because you don't find a particular combination of drums shown in a catalog does not in any way mean they aren't "authentic".
Thank you very much for the information. .. my doubt is if the shells are Superclassic 4 layers or Classic 6 layers? I think there are four layers ... but I'm not sure. The seller told me that the kit was a classic maple of 98 ... but obviously not, because the stamped date is 074 and I've seen kits from 1998 ...
