Hi!
I asume you are a Denison with a Gorham-Howland tie-in? I have eight Denison lines but no Howland line. Check out The Denison Society web site on the Internet for assistance. The John Howland group has a society and Internet presence.
Denison reunion in Mystic, Connecticut; this year in September. FYI: Avery in Groton, Connecticut; in July,; A number of Avery's have Denison lines,.
Relatively yours,
Scott Bill Hirst
