Hi, try the guys at the Weybourne Military Museum in Norfolk as they have one in their collection but as I remember it as soon as the layer had fired, the breech was pulled open ready for the next shell, so the carrier would have been down. Incidentally in case you didn't know the American ammo we used weighed 96lb and the British ammo 92lb so you can see why we had a tray for the shell! You also called it an auto loader and there was nothing automatic about it, it was pushed up to the breech by hand ready for the shell to be rammed into the rifling. Do you have the Foden gun tractor to pull it? And does your gun still have the self propel VW engine? Along with the crew cab (Wendy house) the gun tractor had an Atlas crane which was an essential piece of kit when pulling out the breech for cleaning as it weighed 308lb, which is also the weight of the muzzle so beware if you ever unscrew that bad boy off the barrell :cool2:
