As this thread has been dormant for awhile, and has drifted a bit since 2015 so I thought I might liven things up a bit with a couple pictures of another .405 Win Double Rifle. Please excuse the poor photos, Winter afternoon light is a hinderance.

A little Belgian .405 from unknown maker, proof date code 1926. Sourced from Champlin/George Caswell some years ago.
25 1/2" barrels and a svelte 6 lbs 10 oz with pristine bores.
14 3/8" LOP to a checkered wood butt.

Seems likely to have been brought here after WWII?

ADDED: better light pictures buttstock wood
