After finishing as a works rider Bill Martin went to work with my dad in Newton Abbot. As a 15 yr old I was lucky enough to be taught to ride by Bill on his ex works James, which he had been presented with when he left the company. I will look out some old photo's and see if it was this bike. I have a feeling it was. Bill was riding a Bultaco by then in 1968 and still loving his trials.
