There is a Chuck Schwark listed as the Web Page administrator for the Antique Wireless Association http://www.antiquewireless.org/otb/contact.htm
Official Journal of the Antique Wireless Association, Inc.
Web Page Administrator Chuck Schwark
Amateur Radio Tim Walker, W1GIG
that might account for an old Hallicrafters glowing
there is also a webpage http://www.dealamerica.com/balinks.htm
that has a link to: "CHUCK SCHWARK'S PAGE"
but the link-- http://members.aol.com/caschwark/index.htm
-- is dead
not sure if that is helpful or not... if it sounds like your uncle, you might contact that organization or perhaps W1GIG listed above...
