Brian – I compared the single’s tank with those on the Raleigh stand at Stafford a few years ago with the help of one of the Raleigh club’s officials. Although the tanks are the same size the filler caps are in different places. Also Raleigh continued to use the same size tanks from 1929 until 1933 when it ceased production – i.e. after the Scott ceased production. Consequently, I suspect that the tanks used by Scott were supplied by Raleigh (or its supplier) but were not necessarily surplus/obsolete items. Interestingly, the Raleigh official had heard that Scott used surplus Raleigh tanks but came to the same conclusion as I did once we had made the comparison.
