UPDATE II: See the latest — The Van is headed West.
From August, 2011: Glenn recognized the Willys Van for sale. Even more impressive, he found a brochure for one! Well done! He bought the Sales Folder off eBay about a year and a half ago. Mfg. by Plaza Motors, Inc. Englewood, NJ and was Willys-Overland Factory Approved.
Based on the emails between Colin and Glenn, there were at least three groups of Willys-Overland Delivery Trucks produced:
1) One group was produced during or just prior to WWII (as seen below)
Here is a 1942 Panel Delivery Truck:
2) One group was produced during post WWII and pre 1950, which appears to include the Willys Van owned by Mike. The brochure provided by Glenn also appears to be related to this second group.
3) One group was produced between 1951 and 1953, based on these serial numbers.
The numbers below are for post 1950 FJs. This one appears to be a pre-1950 FJ. We are still awaiting a serial number.
1951 FJ 451 GC1 10001— none
1953 FJ 452 GC2 10001—10065 65 built
1954 FJ454 GC2 10001—10012 12 built
