For their final year in 1933, the Gloria model had a 147cc Villiers engine. Subsequently Triumph sold their own brand of lightweights for that end of the market, before concentrating on their larger singles and twins until after WWII.
One source says that they were manufactured by Triumph from 1932 to 1934, and one of Roy Bacon's books has an image of a Gloria of 1933 vintage.
There is also a mention of the Triumph Gloria for 1924-1925, and Gloria models with Train engines marketed by Triumph France.
