Which marque did Charlie Collier ride to win the 1907 Single Cylinder class?

Charlie Collier rode a Matchless-JAP to win the 1907 Single Cylinder class. His victory made him the first winner of an Isle of Man TT race.

Collier completed the 10-lap St John’s Short Course in 4 hours 8 minutes 8 seconds, averaging 38.21 mph. The Matchless was built by H. Collier & Sons, the family company associated with Charlie and his brother Harry, while JAP supplied the engine. The result was therefore commonly identified as a Matchless-JAP machine.

The 1907 meeting was the inaugural International Auto-Cycle Tourist Trophy for motorcycles. It featured separate Single Cylinder and Twin Cylinder classes, reflecting the engine technology of the period. Collier won the former, while Rem Fowler took the Twin Cylinder class on a Norton-Peugeot.

A likely source of confusion is the 1907 results table, which may shorten the machine’s name to Matchless or list the engine and motorcycle marques separately. The fuller marque description, Matchless-JAP, is the canonical answer for this question.
