I appreciated this great site and got appropriate help through "Contact", thanks guys !
I had a special interest : belonging until recently (I moved...) to a great association in France that struggles to preserve WWII heavy vehicles, I had them to buy a Brockway C666 that slept outdoors in a scrpyard for over 50 years. I started restauration. Big undertaking ! Then I had to move but others continue the task (www.univem-paris.com).
I was very glad to browse in 17th Engineers site.
Thanks again, guys, great job of memory...
