Career
From 1922 to 1940 he also marketed his own brand of motorcycle, New Gerrard. Riding these bikes, he competed in the 1922 Junior TT, but retired early. During practices for the 1927 TT races, he suffered a badly cut face after a collision with a Norton motorcycle ridden by H. Mathews.
Glasgow Museums have Porter"s New Gerrard Blackburne 248cc of 1923 in their collection, having acquired it in 1976.
As of 2015, it is in storage, and so not on public display. In 2008, two albums of photographs and postcards of TT races, from 1921 onwards, which once belonged to Porter, were sold at auction by Bonhams for £3,220 (including premium).
