I picked up this small, no name engraved Mannlicher style bolt rifle in what I think is 22 Vierling caliber.
Some proofs and markings on the bottom of it's full round bbl and Crown/B,U,G proofs on the action and bolt along w/a ser#.
4 shot straightline feed magazine detachable by swinging the Mannlicher Schoenauer style floor plate to the side and simply dropping it out of the rifle.
DST, 2 leaf rear bbl sight as commonly seen on it's big brother rifles. A spring loaded 'Peep Sight' or better termed,,a diopter sight I believe at the rear that hinges away with the operation of the bolt.
Just thought it was a neat little rifle. Needs some work. I'm suspicious that the chamber may have been opened to 22 Hornet,,I'll have to do a chamber cast, ect.
The internal magazine is a replacement made from a commercial product but well adapted and fitted. The butt stock was stuffed full of lead 8mm rifle bullets in a bored out cavity to give it some xtra weight! Thats out of there now. The butt plate is a simple horn plate.

A few pics... The rifle round in the first pic is a 8x57J,,the steel ruler is a standard 6 inch.
