This WWII artillery served until just recently. They had either an 8 inch or 155 mm gun barrel. I saw one a few years ago being used to test liquid propellant explosive, probably at Yuma testing grounds. Same everything, but the barrel had several more bands around it and the loading was automatic from some mechanism at the breech.
The other end of the inventory, the WWII US Army 37mm ATG. Note the huge 155 barrel over it and how small it is in comparison to the wheels of the large howitzer.
Can you guess what this is? One of the most important guns of WWII that Roco never made. I have to use the Airfix one in 1/76th scale.
The 40mm Bofors guns were used by armies and navies on both sides of WWII! This gun looks like it was in service this morning, it is in perfect shape.
A humble US Navy Jeep, driving out of a landing craft. By switching service you can make some interesting vehicles out of existing kits. Naturally the Jeep was used by the Army, Navy and Marines in WWII. The M113 APC was used by the Army, of course, but also NASA! I have also seen an M60 series tank in US Air Force markings. What did you do in the Air Force? I was a tanker! You don't hear that too often.
