I sent in a photo back in June of a JE
in seemingly racing trim with registration number OX4843. And here it is again - in Motor Cycling for May 9th. 1928. Note the dry-sump crankcases. Unlike the ES2 during the Vintage era, I do not think any dry-sump JEs were sold to the general public and I have not heard of even the remains of one of these works engines. A friend of mine who saw the previous photograph commented that the speedo was fitted so that the rider could see how really slowly
he was progressing along the highway......
