Once again, I'll state that "vintage" is a rather meaningless term to categorize drums as to their collectibility or desirability. I prefer to delineate the categories of drums or many other things by the era in which they were produced. Vintage is intended to identify the year in which a particular bottle of WINE was made. That's wine--not drums or cars or pottery. The "vint" refers to vines of grapes. There are Civil War era drums, Victorian era drums, Jazz era drums, Pre-World War Two era drums, Big Band era 1930's--1940's drums, mid 20th century drums from the 1950's-1960's, and the eras following these. In my opinion, if you insist on using the word vintage, that word should be immediately followed by a specific year such as vintage 1953 Slingerland or vintage 1989 Tama.
"vintage" enters as a common linguistic term to identify still usable objects of an era immediately prior to ours, of some interest in design, performance or for reasons of pure nostalgia, an object that does not interest anyone remains trash even if old, I'll have to become "ancient" to end up in some museum
However the forum is called vdf and we do not talk about wine!
