Bob/John:
Not to throw cold water on a cold trail but I think the chance that the old boy with the "Dead Sea scrolls" was a Winterthur-trained conservator/restorer is a long one. There were a lot of vintage tool collectors in the sixties and seventies and busloads of them knew it all but had no affiliation with Winterthur or Williamsburg or the E.A.I.A and although they "knew it all" to a man, a lot of them were simply catalog numbers runners and decor-and-curiosity collectors. However, I have a couple of friends at Winterthur who might be able to hook me up if I know precisely what question/s to ask. Are you looking for Winterthur-trained pro or am with address southern Illinios?
