Hi,
An original dual seat believed to be off a BSA A7/10 swinging arm or B31 (or simialar BSA) - the base is in reasonable condition for age, the cover needs repairing or replacing and the foam does need replacing. One locating tab needs minor repairing - but not a hard job - see photos. Collection is preferred but will post at cost which is additional to selling price. So, £35 + postage or £35 collection from the East Midlands.
Cheers
RR
