Norton International - 2.5" Butterfly Oil Filler Cap (and OHV/SV Petrol Tank)

- Modern Reproduction of the classic 2.5" butterfly filler cap, as used on Norton International oil tanks (as well as pushrod and sidevalve petrol tanks). Notice: These fillers come from offshore and as supplied to me do not have the cork sealing washer - which I think is pretty poor - so I buy those separately and make and fit them before sending out (if buying from elsewhere you may want to check they come with washers!)
