It is indeed a chunk of cash but it is less expensive than what any of the other London makers would have charged you for a similar rifle. Having seen newly-made examples of just about all the "name" British makers recently, including a few so-called "Centenary" models from H&H, I can assure you that the Vintage and London Best Rigby's are a cut above the res, quality-wise.

In years to come, the fact that the Rigby name is on the barrel will also help the rifle to appreciate in value.

Labour, rent and the general cost of living is expensive in London, as are newly-made Magnum Mauser actions. That accounts for a huge chunk of the price.

You cannot compare Rigby prices with those charged by US custom makers. They operate in separate universes. We don't have to like it, but it's a fact.

And the Vintage model is not the same gun as the Big Game, by the way. It is handmade whereas the Big Game is largely machine-made.
