I needed some support equipment for my display case and was glad to see Airfix do this set, I wish they would also do it in 1/48. The tank trailer, the Autocar tractor pulling it, the bomb truck and trailer, and the Cushman scooter are in the set. The dump truck is a very early Hasegawa kit as is the jeep, had to scratch the clear parts because they were never a part of the kits. The other GMC 353 is by Academy and is a nice kit, although I had to reshape the windshield on it. I am familiar with the GMC trucks as my family used them in a water well drilling business after the war when I was a flea. I worked on the 270 engine many times although most were in later post war trucks. The frame and drivetrain on the Academy kit is very complete and accurate. In comparison the Hasegawa kit is very simplified but still more fiddley to put together, and I am offended that they got the rear suspension springs upside down. How's that gonna work? However, this dump truck built a lot of airfields in WWII so we all need one or three, right? The C-53 is the Airfix kit, built previously.
