I have a "Hupmobile Construction Details Including The Use of Metals" booklet. Inside cover indicates Copyright 1922 by Hupp Motor Car Corporation. Tenth Edition December 15, 1922.
I found this booklet in a box of stuff my father in-law had kept for umpteen years. If this is something anyone with an interest in Hupmobiles would like I will be glad to send it to you. Otherwise, it probably will end up in the trash.
