UPDATE: **SOLD** Was on eBay
Here’s a rare letter that advertises woodie kits from Station Wagons, Inc, for CJ-2A and MB/GPW models. This 2 page letter shows both a full and a half cab. Below the two page letter is an example of an ad that appeared in Popular Mechanics.
Popular Mechanics Ad from the January 1948 issue of Popular Mechanics, pg 266. This ad appeared in the February 1948 issue as well. I haven’t done a full accounting to determine how many other issues had the ad.
