The postbag

The postbag I receive is never dull. Recent enquiries have included one from the owner of the replica of the D6-75 Delage with which the French driver Gerard won the 1938 TT and drove subsequently at Brooklands. He asks what shade of blue the original car was painted. I once followed Gerard into Brooklands when he was driving there on a practice day, but I cannot remember. But maybe someone else will?
