Sorry Marco - you have a slight problem!!

Highest number in the 1948 Senior TT was No 70.

The Lightweight was run alongside the Senior, with numbers starting at 71 - no 92 there was Jock McCredie on a 250 Excelsior Manxman.

The Junior TT had a No 92 - David Whitworth on a Velocette KTT.

Nice to hear from you again - is this any help??
