I think that's John Shirley.

Responsible for bringing CNC to Holland and Holland in the mid 80s.

South African.

Believe he did a single shot action .............sold to Giles Whitmore (?).

Ian Clark, formerly of Holland and Holland and Purdey (machine shop, joint resurrector of the Rising bite, big hand in the damascas Purdeys, .410 scaled Purdeys.....etc) was employed by him at one stage.

Shooting Sportsman did an article on Ian Clark and it mentioned John Shirley and his input/association with CNC and the gun trade.

Didn't know he'd actually hung up his shingle as a gun maker.
