Hi Carl, I think this bike is older than you think it is.Excelsior made a Talisman in 1949 with a 244cc two stroke engine.In 1953 they came out with the Talisman Sport.In 1959 the engine size went to 328cc.Excelsior built bikes for the military, a 98cc Welbike and the Sprite for the Corgi company.There was a 98cc Consort.These were from the war years,39-45.Good luck.
