Mystery double in mystery caliber
#389488 - 09/02/25 05:46 AM

I was asked if I could help regognizing this double rifles maker and caliber. Looks like it has been made in Germany, probably before WWII. That Sosnowski was probably polish gunshop who ordered and then sold that rifle. I was told that rifle has been owned by finnish general. The only caliber marking is 10,3 mm so maybe Kuduae or lancaster would know that caliber.

Great looking rifle you have there Igorrock!
Love the engraving - beautiful!
Yep best bet will be either Kuduae or lancaster, I think though that there were a few variations of the 10.3mm cartridges?

I’d say it’s either a 10.75R Grundig or a 10.75X52 Springer

Do a chamber cast and see if it is a straight walled case - the Grundig, or a bottle neck case - the Springer.

10.3mm is the bore - the bullet will be 10.75mm and 340grs

yes, one of them and like huvius said straight or bottle necked

to see this it would be enough to make the chamber cast with paraffin

Thanks for the replies. I will have a chamfer later cast later but it seems, according these first measurements the caliber would be 10,75 x 52R Springer.

Fits nicely into the thread on straight gripped double rifles.
This example I really like - more than most!

I looked to see if it had detachable sidelocks. Because it looks like and has the same engraving patterns as my Azhur shotgun. But of course that is a copy of an H & H design as well.

It's a classic design all over. Quite British and IMO not very German-like look.

I imagine a 10.75x52R would be a quite mild medium game cartridge. 340 grs at a moderate velocity. Adequate for moose and bear in the Finnish forests.

It would be nice to know who was the maker. Is it possible from Suhl ?

EDIT: It seems that Sosnowski have had co-operation with W.F.HEYM, Suhl so this rifle could be made by them. This is their original Add:

The action is similar to my Springer which was a 10.75 when originally made.
It's a "sideplate boxlock" which is just as it sounds. A nice stylistic way of making a boxlock look like a sidelock and offer a nice palate for more engraving.

the proof marks will tell a story.
the Springer's Erben double rifles in 10,75x52R were made in Liege/Belgium so having belgian proof marks.
a common double rifle in 10,75x52R Gründig was made for Gründig/Dresden by Sauer&Sohn so having Suhl proof marks.

but I say common, they were never common.

springer's erben catalog, early 1920s,iirc

they offer a hammerless double rifle, here Doppelstutzen ( very austrian)

and single shot stalking rifle with hammer

here I have pictures of an original

I think those small stamps in my last barral photo are one key when searching the maker. Two rhombus with something inside are mystery to me. I found one old discussion from Double gun journal -forum where people trying to determine apparently similar rifles maker. There is a link to photo but it doesn´t work anymore.

the proof marks are german and this would imho exclude a rifle deliefered by Springer's Erben in Vienna.

the 22 gramm bullet proof weight is my problem

the bullet weight for the 10,75x52R Gründig would be 22,5 gramm.
if for the Gründig cartridge I find the lack of precision disturbing.

anyway, you have to made a chamber cast, straight or shoulder thats the final question.
if its the Gründig cartridge there is a chance this double was made by Sauer&Sohn.
