I couldn't afford that sort of money but I believe "names" associated do increase the value of the rifle.

In the end what people are willing to pay for it, is the value it will receive on sale.

I like firearms with a history. I also collect weapons - swords, axes etc - and the Japanese believe the souls of the owners stay with the katana (two handed sword).

Sort of with double rifles.

Each double rifle should have a ledger of its life and happenings.

I wonder if that would also increase its value. Maybe not "it sat in a display case in my den with forty others and never ventured anywhere". Oops!

The belief in souls staying with a Katana is good reason never to sell one back to its country of origin in my opinion.
