Barney from Barney’s Jeep Parts sent November 1961 edition of the Jeep News our direction. The FJ-3A makes a big splash with a variety of images on page 4. Several Jeep Clubs, including California’s Auburn Jeep Club, Denver’s Mile-High Jeep Club, and Washington’s Trailer Breakers Jeep Club get mentioned. One article highlight’s Buddy’s win of a Surrey and Sailboat from the Del Monte Contest and includes an image.
There’s also a mention of photos and writeup about the Jeep Jamboree in the December 1961 issue of Argosy Magazine, but I cannot seem to find the issue on eBay.
