1936 Brough Superior 990cc SS100
Registration no. CTO 147
Frame no. M1/1627
Engine no. BS/X2 1002 (see text)

• Long term ownership of over 50 years
• The 5th MX100 to leave the factory
• Original frame and engine no. pairing

CTO 147 was the fifth Matchless powered Brough Superior SS100 to leave the Nottingham factory.

A retired motorcycle dealer, the vendor has known this machine for over seventy years. As a schoolboy he was given lifts sitting on its petrol tank by the previous owner, a plasterer's labourer. Some years later, after several unsuccessful attempts, he eventually succeeded in buying it for the grand sum of £15, although by this stage the Brough was in a dismantled state.

A skilled engineer, he restored it, both mechanically and cosmetically, to a very high standard. We are told that the recorded mileage of 6,268 is the distance covered since that restoration in the late 1960s, at which time a new speedometer had been fitted. A photo shows the bike being ridden on Pendine Sands during one Brough Superior Club event when the owner clearly remembers seeing 90 mph on the speedometer. It was used in many other club events prior to a spell of ill health which restricted his activities. During this period the Brough was laid up, but unfortunately the previously bone dry storage area became damp because of drainage problems from a neighbouring house and garden. By the time the vendor became aware of this situation, the SS100's previously excellent cosmetic condition had sadly deteriorated. However, it should be noted that the engine turns over with some compression, and all gears can be selected, although we did find some false neutrals when rotating the rear wheel. Recommissioning and some restoration will obviously be required to a greater or lesser extent to return it to its former glory. A V5C registration document is supplied. No keys are either required or present.

Mike Leatherdale, the highly respected registrar of the Brough Superior Club, tells us that the engine numbers of the Matchless powered machines were stamped at the AMC factory before the engines were despatched to Nottingham. With the introduction of the new overhead valve engines there was apparently a change of mind at AMC with regard to the number sequencing compared to the pre-existing side valve power units – and this is the reason that some of the very earliest ohv engines have over-stamped numbers. The 1936 Works Record Card for CT0 147 originally recorded engine no. 4002 but the factory changed this in ink to read 1002. Meanwhile, it should be noted that the V5C registration document records the original 4002 number rather than 1002, in the incorrect form of BSX/2.4002. The later 1939 Works Record Card shows the engine no. prefix as BS/X rather than the expected BS/X2 – perhaps the result of a clerical error?

However, in a letter to us dated 2.8.21 Mike Leatherdale writes "I am happy that the BS/X2 1002 is a genuine AMC stamping".

CTO 147's frame and engine are the original pairing. As indicated above, there are two Works Record Cards for this SS100 (the original cards are retained by the Brough Superior Club, but Club issued copies are supplied with this machine). The first card relates to its original supply in June 1936, while the second dated 13th November 1939 presumably indicates its despatch following a return to the works. Referring to the second card, Mike advised "Don't be confused over the different wheel and tyre sizes, this is simply a change in the way measured between '36 and '39, and the non-voltage control dynamo system just shows it still had '36 equipment".

This SS100 is offered for sale with considerable regret, and only because of the vendor's advancing years and recent ill health. Prospective bidders must satisfy themselves as to the motorcycle's completeness and mechanical condition prior to bidding. Sold strictly as viewed.

A wonderful opportunity to purchase one of the earliest Matchless powered SS100s which is ripe for restoration!
