CC were motorcycles produced from 1921 to 1924.
The name came from the initials of the maker - Charles Chamberlain - of Blackpool.
Various models were listed in a range of engine capacities, made by either Blackburne or Villiers. Some were single speed only, but most had chain-cum-belt transmission. The engines ranged in size from 147cc to 996cc. They appeared rarely in trade publications and were not otherwise well known.
