This Essential Special Service Tools for Trucks brochure by the Miller Manufacturing Company appears to have been first published in January of 1948. It was then updated with this second edition in December of 1948.
These aren’t best scans. so I’ve had to do repairs in Photoshop. I’ve actually had this digital brochure scan for several years, but finally had a chance to assembled the scans yesterday, after Maury noted that this has the Willys sign, which would make it the latest document we’ve found with the Willys-Cars-Trucks-J sign on it. There’s a companion brochure for CJ-2As in the post above.
