Wow -- get photos and post them here.
Complete coverage including details of all barrel markings and action flats too.
Get very good detail all around the wrist and head of the stock.
Breech faces, barrel breeches, muzzles, and a peek down the bores.
Get images of the sights and the ribs.

A Bland in 275 will be a very very cool little rifle.
You should be seeing some of the best work of it's era.

Price will depend on condition.
