A lot of people get their panties in a wad over the California Rigby era.
I think his name was Geoff Miller, I can't remember the entire story. He bought the records or name of Rigby from someone in the UK. Then brought in American and maybe 1-2 British/European gunmakers to build guns. One of the stranger aspects was that his double rifles were made on Merkel actions.
I have handled them, and the best of them (bolt action 416) are as good as any rifle made in the UK. Their designs were mostly their own, they weren't exactly built in the same tradition as Rigby rifles were of old.
When Blaser registered the trademark Rigby again about 10 years ago, my understanding is that Geoff had never registered the name outside of the US.
I don't think Rigby (Blaser) nor Rigby (USA) is really Rigby. The Roberts era Rigby would certainly be closer to being Rigby than either one of these are. At least Blaser based their rifles on classical Rigbys.
This is my opinion, but I believe Blaser has done more to return Rigby to a top shelf company than Geoff or Paul Roberts ever did. Though just like Blaser (even though I own 3 Blaser's), the brand is more of an image brand that the reality that it is a substantially better mousetrap than a Weatherby Mark V, Winchester M70 or mid-grade 700 clone.
