Raleigh still own some of Reg Harris's track machines and have the original Professional Sprint Championship track iron that was dusted off in 1972 now on permanent display plus plenty of others from the Raleigh racing stable that start from the beginning of the last century until the early 1980's at their museum site in the Brooklands Museum in Surrey. I was there two weeks ago and can vouch for a good, nostalgic day out if you're ever in that area, regards Griff King-Spooner (London UK)
