lol "Assorted Hardwoods""Assorted Hardwoods" would probably be the best description.
Ghostin one's comments are a good refelction in how far along drum building technology has come along.
That we've gotten to a point, for some time now I might add, where even an entry level series drum can be a viable candidate for one who wants/needs to gig at an affordable price point.
However, rest assured, that in the hierarchy of Ludwig drum models, the "Accent" (CS, Custom or otherwise) is their Entry Level series.
I don't think the serial numbers will correspond with the accumulated list of Ludwig serial's, as far as determining the age of the drums, but that is speculation on my part.
Best thing to do, about that, is to write to Ludwig and ask them yourself.
