Rare 1915 Ross MKIII sniper rifle

[Claven2]

FWIW, we do know the collector who owned it was NOT in the military. (he actually died closer to 20 years ago and the rifle had been collecting dust in a basement closet ever since along with some nice Purdy double rifles and a Purdy 8 Gauge shotgun - don't ask what those sold for!). The story goes he bought most of his collection in the 1930's during the depression when some previously wealthy people fell on hard times and he only bought nice stuff. This and one or two other rifles plus a some WW1 Lugers were the only military guns when the collection was liquidated (in two batches, one about 15 years ago, and the last few pieces this year).

We also know his last name was Armstrong but we were unable to determine his first name. Whether he made the markings on the bottom metal are anyone's guess.

Has anyone noticed how much colour case remains on the bolt and bolt stop? The bore is perfect and this rifle is low-mileage. Definitely. I should know, it spent some time in my gun rack before it was delivered to Badger
