    She is a beauty - I need to get a muzzle cover or find a bit of canvas. I don't suppose you know if the breech is held down with any locking mechanism or does the autoloader need to be in a certain position? I'm trying to open the sliding breech so I can have a go at cleaning it inside - but it's jammed somehow - it does not look too rusty.

    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

    Hi Wally, that's fantastic, thank you very much for the info. Do you know what the SA Gear does that is marked on your diagram?
    Also, how hard do you think it is to take the whole breech block off to service all the parts? Would loads of springs and parts drop out never to be refitted correctly ( this seems to happen to me a lot!).
    Regards Bruce

    SA gear is semi-automatic gear, this opens the breech on runout. I have no knowledge of FH70 but it usually has a manual setting which will keep the breech closed on runout.

    It will come out in one piece but as I said in an earlier post it's a heavy lump, a steady smooth vertical lift and she'll pop out no problem. Saw from an earlier post that I hadn't read that you still have the engine, which a least saves you from the hassle of cupelling up to an auxiliary hydraulic source to raise and lower onto the plate etc. Only ever fired the gun with the spades dug in when on the anti tank range at Lulworth, can't remember the exact charge bag but got a feeling it was number 7 but I'll never forget the violence of the gun when she fired! Those spades really did need to be dug into a hole.

    I've been out of the mob since 96 but it's nice to talk about these guns again.

    One day it will be restored and you can come and show us how to use it! We are based in Shropshire.

    It's not the handiest of military history to move around due to its size and weight. I need to work out why it won't fold back on itself - maybe the wheels need to be fully down - the hydraulics are a bit temperamental (like me!).
