Proof Marks on a 9.3x57 Oberndorf
#387067 - 05/10/24 03:13 AM

My buddy just picked up a 9.3x57 Oberndorf with matching serial numbers that puts it manufactured in 1924-1925. But the proof marks include the crown over N and there is an extra set of proofs on the left with the top proof I can’t make out. I understand the crown over N proof didn’t start until the late 1930s.
So how does the 1925-25 date of manufacture work with the crown over N and what is with the extra set of proof marks?

The second set of proofmarks are crown/R = repair proof and crown/U = inspection after proof firing. Most likely the rifle got a new barrel in the1930s. At the same time the now necessary crown/N = Nitro was added to the original proofmarks. The new barrel was numbered to the receiver, as was customary at the Mauser factory.

Kuduae,
Awesome, thanks for the quick reply.
Now, if I can only figure out how to reduce the size of the stupid image… 😞

I resize all my pictures for sites that require a maximun size or smaller, is my paint app that is available if I right click on the picture in my computer, then click on "edit". I selected re-size, then usually, if it's 3 meg or over, set it at 30% or 40% and click the X. That brings up a screen "save as", which I do and that converts the picture to between 600 and 700 kg.
Then you have to transfer your picture to an online upload site, or send it to a different forum with a "straight from your computer upload system" so it gets "published" to the internet. Then THAT address can be uploaded to this forum within the brackets [IMG] and [/IMH].
Most guys here is an upload site.
