Here is as complete a list of Henri's rally results as I can put together. The accuracy of the earlier events is a little dubious - especially with respect to co-driver identity, as the greater portion of my material comes from 1980 onwards.

A point to take note of is the championship eligibility for different events. There are actually two British rally championships, the National (restricted) and the Open. Some of the events run in the UK form a part of both, whereas others are unique to each series. For instance, the Manx Trophy is part of the National series, whereas the Manx International is part of the Open Championship.

On a similar tack, this also applies to the European Rally Championship, which has no programme specific to itself. All the rounds - some thirty in all - eligible to count for the title are actually premier events from all the major national championships, graded according to difficulty. So events such as the Manx International, Ypres 24 Hours, Costa Smeralda and the Arctic Rally are all part of the European Championship.
