Hi, Phillip:
I own a pair of Vandy 3A Sig's, but giving you their serial numbers won't help much. Sorry you weren't satisfied with Richard Vandersteen's response. Personally, I'd accept his answer regarding the speaker's age. Richard may sometimes seem abrupt on the phone (though I have never found him so), but in my half-dozen conversations with Richard I have always found him to be very honest and direct. I can't think of anyone in a better position to know the "vintage" of a speaker than Richard.
If you still want a "second opinion" regarding the age of the speakers, try calling a couple of Vandersteen dealers and see what they can tell you.
