Colin Washbourne's foot can just be seen poking underneath the white sheet he held-up behind the bike for the BSA works photographer.

The 1954 twins
	Distinguishing features of the '54 bikes are the open megaphones, fabricated rear brake lever and pivot, alloy damper know, butterfly filler cap and no stays on the front mudguard. Some of the fabricated and lightened items such as the top yoke were direct copies of items Roland Pike made for his own earlier BSA special Gold Star
	Although the rear guards at Daytona had alloy extensions as shown in the 55 pics below, these were fitted to the bikes raced in 54. Why they aren't shown on Colin's pics, we don't know!
The 1955 twins
	Distinguishing features of the '55 bikes are the reverse cone megaphone, monza filler cap, stays on front mudguard and standard rear brake lever and linkage. Compared with the 54 bikes the 55 bikes seem to have used more standard production items for small details parts.
	For example the rear brake and linkage appear to be standard Gold Star and the front engine plates standard with contoured edges - the 54 plates are straight cut Since many of these items on the 54 bikes were the result of Roland Pike's original prototype thinking it may be that these were replaced with standard items once Pike had left BSA in 1955.
