Utility was first introduced in 1941 under the CC41 mark and at first it was used only for clothing . Furniture was next and then other items were incorporated into the scheme. Utility Clothing was introduced by the British government with several purposes in mind.
Raw materials (cloth, wool, leather etc.) were in short supply and had to be conserved. Manufactures needed to become more efficient in their working practices (Much of the skilled labour had left to fight). Clothing prices (which were increasing) needed to be kept down so that the civilian population could afford clothing of a reasonable quality. The scheme extended to furniture now highly collected and other essential items such as some bicycle parts. The utility scheme continued past the war until it was finally withdrawn in 1952. The CC41 mark is two C's which look like "PackMan" but it stands for Civilian Clothing but it extended to a whole host of things. Suntour Superbe Pro was certainly available within the CR time-line. I had by Harry Quinnn fitted with this group kit in August 1981
Thats all for now. Keep those wheels spinning, in your memories if not still on the road. Be lucky Mick Butler Huntingdon UK.
