New Gerrard were motorcycles produced from 1922 to 1940 by Jock Porter of Porter's Motor Mart, Edinburgh.
At one point, his road models were built by Campion of Nottingham, but he mostly designed, built and raced the machines himself.
1922 Jock Porter entered the Junior TT but retired early.
1923 The marque made its name at the TT when he won the 250cc.
1925 Only Blackburne engines were used; these were of 249cc or 348cc with sv or ohv. A New Gerrard came third in the 175cc class at the TT.
1926 Only the 348cc models were produced, but these were later joined by one of 549cc.
1929 Only the 348cc ohv model was listed. This came in both road and racing versions.
1930 The engine changed to a 346cc JAP, and the one model continued to be listed throughout the decade.
