1911 7D for sale on eBay
This great 7D has just been listed on eBay. It has the same motor as my 8D, the only difference as far as I know being the B suffix after the letter A.
Letter A for 1911 with the smaller 50ci motor. Letter B for the first ‘big twin’ 61ci motorĀ in 1912 and letters AB for the very early 1912 still with the smaller motor before the change to the larger 8E. This was presumably to utilise the remaining stocks of the 50ci motors already manufactured.
