Cork Washer for Norton 3" Butterfly Cap

This is a replacement cork sealing washer to fit the 3" butterfly cap fitted to Norton SOHC International and Manx petrol and oil tank caps (the caps can be ordered separately - Item 0120)

We have to cut these out specially, as we have found all other ones available do not fit properly- very fiddly (and apologies if occasionally we leave a small amount of marker pen on them - but it does not detract from their purpose!) - and we dont get many per sheet of cork!  . .. we have little jigs for marking these out . ..and I find myself (or my daughter Steph) cutting them out while watching an F1 grandprix on a Sunday afternoon . . . very time consuming!
