Anyone know what gun this is?
 

I don't know the model but a discussion on reddit concluded the ammo to be the following.

Okay, several Russian sites state that to be "An Old German Gun", however I cannot find a page with it actually on.

However, I have found 2 gunsmiths with similar guns.

It is a .... "So you think you want to marry my daughter" gun.

Its a german high price huntig rifle/ shotgun.

Vierling = four barrels

Drilling = three barrels

In good old days in Germany there were legal restrictions on how many weapons you could own. Vierling or drilling is nice legal way to avoid those restrictions. After all you have shotgun, small- and large caliber rifle in same gun.

Those restrictions are long gone, but drillings are still weapon of choice (in Finland at least)to some hunters, who have nostalgic ideas about wild boar hunting in East Prussia (and have extra cash- those guns are quite expensive).:)

Here an example of three barrel

Its a gun I want to own and put over the fireplace.

I thinking thses types are called over under guns or muilt barrel slide lock

Guns that decorated and of that type are usually hunting/ceremonial guns. Chiappa just released a triple barrel shotgun Chiappa Triple Threat at the Range: http://youtu.be/Yt0664xSKUo

A mongo-deluxe Dreiling.

If I had the spare cash I would like a nice Holland and Holland double rifle...
