I'm trying to identify the aluminum alloy used for the front and rear shrouds on my 56 BN4. Does anybody have the info, or if there is an updated compatible equivalent? I need to do some patching, and don't want to screw it up! Thanks for any help I can get![/QUO
16 S.W.G. aluminium-manganese alloy to B.S. 1470 N.S.3.
