Jubilee 1958-66. 249cc, ohv twin, 350lb, 75mpg, 65mph.

Well designed but underdeveloped and badly constructed unit construction twin in AMC group lightweight chassis. Most engines rattle and leak oil. The Deluxe version looks quite smart. Not to be confused with the Triumph Sliver Jubilee.

Navigator 1960-65. 349cc, ohv twin, 350lb, 65mpg, 75mph.

Enlarged and more useful Jubilee with road-holder forks and an 8" front brake. Enough performance for cruising the byways and excellent handling.

Electra 1963-65, 394cc, ohv twin, 360lb, 55mpg, 75mph.

Rare electric start version of the Navigator with a bit bigger capacity and indicators. Not a bad lightweight machine with elegance.

International Model 40 1946-58, 349cc, ohc single, 340lb, 65mpg, 85mph.

This is a fussy camshaft model based on the Manx Racing Norton. The Featherbed models are the best but they are ludicrously expensive.

Model 50 1956-63, 348cc, ohv single, 400lb, 75mpg, 75mph.

A gentle traditional British single with nice manners, but a little down on performance. Post '59 models are the ones to buy with the famous Featherbed Frame, decent lights and good looks. Very few survive, most were built into Tritons. The engine is vice-less and the steering is excellent.
