Ron, If that's the case then I'm fairly certain that the bolt on my old rifle was fitted by Parker Hale when they reworked the returned C3s into target rifles and/or M82's. IIRC the bolt had Birmingham 20T proof marks that matched those on the rifle and the style and position of the electro-stencilled serial on the bolt is exactly the same as on my other M82, so I'm convinced that the "tactical" style bolt was a PH factory fit during the rework. I think the M87 (used by UK police) also had that style of bolt handle.
