Nut, axle spindle, Norton pre 1947

Wheel nut for front and rear axle spindle assembly for Norton girder forks models. ZP steel. Suit all Norton girder forks from 1932 to 1946. NOTE: Norton used the same part number post 1946 BUT changed the shape of the nut so the thread is open on both ends. This modified version was used on the back axle on later models.
Original part numbers:
9509; A2/454 - front hub spindle nut
9521; A2/454 - Rear Hub Brake Drum and Sprocket Fork End Attachment Piece Nut
