Chris Tattersall retired in the 37TT senior but he had a 6th in the lightweight on his own machine a CTS (not hard to work that name out)
two other riders in 37 senior on HRD senior Eric Oliver (of sidecar fame) and Jack Williams
all retired
There was only one rider in 38 senior on a HRD Manlif Barrington he retired
not a good record for the bike so nobody bothered in 39 then Hitler stopped play .....
