I would think the simple economics of such rifles being desired by more baby boomers who in turn also want an African Hunt would drive the price up substantially.

I'm in my 50's but will ?probably collect Doubles for the next ten years, then maybe look to sell off guns in my 70's.Heaven forbid to think what hunting/firearm prices will be at that time!!

I personally think that Classic Brit rifles/shotguns will be the most desired rifles sought among firearms available for the foreseeable future.
