The 350 cc AJS OHV machines from the twenties got their nickname “Big Port” from the enormous size of the exhaust port and pipe. 
Between 1920 and 1922 AJS was very successful in racing with 350cc ohv machines; their catalogued models then were all side valve machines.  
For the 1923 season the ohv concept was first used for customer models; its official name  was the “2 ¾ hp three speed Overhead valve T.T. model” , but unofficially it immediately became the “Big Port” Ajay. From 1925 on prefixes were used to the numbering system:
E=1925, G=1926, H=1927 K= 1928.
Engine dimensions were 74×81, detachable cylinder head,  three speed AJS countershaft gearbox., speed about 70 miles per hour, weight approximately 90 kilograms.
G6 was the standard machine for 1926, other options that year were the G7 special sports and the G7R special racing model.
This handsome and sporting vintage machine has been nicely restored.
