I've got a few spare copys of this here,
I did notice though that even though you could use the mantlet and the mussel break as there alloy and easy to mod, the barrel is in two parts and not worth allot unless you want a non firing tank
the other thing ive noticed is that the barrel is off set to one side of the mantlet is this correct for a tiger 1 ?
the back of the mantlet has 8 screw mountings on it and other than that is fairly flat so should with minor work fit a heng long tiger 1
