I have been looking at a simply magnificent 416 Rigby built on Magnum Mauser Square Bridge Action the rifle has the Paso Robles, California address. Disparaging remarks are abundant concerning this period in Rigby's history. The rifle I am looking at is flawless, it has all the niceties one would expect. The action has German proofs, does anyone know who built these bolt action rifles? Where did the components originate? Thank you.
