Those knobs look fantastic Gary! If you want to keep those skills finely honed, I can send you my knobs!
I have run across those fuel valves a couple times.http://halftrackinfo.com/index.php?topic=228.0they where also used on the autocrar U7144T trucks
Looking great. That fuel valve set up is about the 3rd or 4th I've seen. I'm sure it is a post WWII modification. Which country, I don't know. French, Israel or other? Keep up the great work.Steve A.
