FWIW, if they released a 50-110 or a 450-400, you wouldn't have many people running chambering reamers into 45-70s.

On the quality issue, I believe that many potential double buyers would buy a hint of rarity and glamour. I would prefer an economy modern double at the base Ruger level of quality and finish for $1800 than a $900 rifle that feels like an SKS. Nevertheless, there were many Lada Niva owners and Toz .22 shooters who got acceptable gear for modest cost.
