OSS, Most of us call it a "cross eyed stock". If you need one, you are lucky to have found it, they are pretty rare. For a front sight, check with New England Custom Guns. We can likely give you some information about it, but you need to post photos of all markings, especially proof marks on the bottom side of the barrels. If it is 8mm there are several possibilities for the nominal chambering. If it is 8x57R, there are still at least 3 possibilities. You may need a chamber cast to sort it out, but maybe not. I think you are in for a lot of fun. Mike

1st pass thru the Steyr proof facility, being a satellite Vienna stamping station, in 1927 w/ the scattergun having a diameter of 15,5 mm and the solid projectile tube @ 7,3mm. Final pass in 1927 was 16,2? and 8,0mm. I've seen that open ended infinity symbol as well as the script M many times.

OSS, Raimey is more familiar than I with Austrian proofs so I will defer to his opinion. As far as the nominal chambering is concerned, the Austrians commonly used a slightly different system of marking than the Germans. Where the Germans marked the barrels normally with the bore( not groove or bullet) diameter, the Austrians often used the groove diameter. This means the groove diameter of your rifle barrel should be around 8mm or .315".This is a little tight, but 8.1mm is .319" whereas we normally consider the 8mm sporting groove diameter as .318". Considering tolerances, we can likely disregard cartridges with .323" bullets. In addition to the common German cartridges, the Austrians also chambered rifles for their own cartridges. All this is a round about way to say you will likely need to make, or have made, a chamber cast to determine the nominal chambering of your rifle. Slugging the barrel will determine the actual groove diameter( or extend the chamber cast into the barrel). If the seller included cartridge cases fired in your rifle, they could be used instead. Mike

Something I omitted is that the tubeset should weigh 1460 grammes. Is the scattergun a 20 bore @ 15*5mm to 16*2mm(?)?

The UK call it a cross over stock. I have bought and sold a few when I was importing/dealing.
