Nice copy of the pillion footrest rubber - as shown in the 1948 Norton Spares catalog . . . which are of the correct type used in conjunction with the pressed steel footrest hangers which were used by Norton's on all Rigid and Plunger framed models of the 1930's/40's/50's.
These ones are also embossed with 'Norton' on them (shown very faintly in the 1955 catalog as being correct), which looks good
