Hi there first time thread, I really enjoy the forum! 
I was wondering if anybody knows anything about these markings? And if it's chambered in regular 8x57 or the older 8mmj.
Anyways it will be sent off to a gunsmith for verification. Btw I'll upload a pic of the entire rifle tomorrow.
Everything matches, right down to the action screws. Thanks for any help! (Hopefully my pics work)

Hope Kuduae jumps in – untill then I'll give it a try
1st pic
N with crown = Nitro proof or semi smokeless powder
7,7mm = .318 caliber – older "I" Mauser not newer .323 "IS"
Now following numbers I am not sure about – one of them is date of make – either
2.13 (2.19) = february 1913 (1919) or 1 25 = january 1925
If 1 25 is january 1925 then 2.13 might be powder load in grams = 2.13 g = 32.87gr
4th pic
Crown with N = Nitro proof for rifled barrels
Upper line is bullet type – can't read but it might be one of the following:
St m G = Stahl Mantel Geschoss (Steel Jacked Bullet)
K m G = Kupfermantelgeschoss (Copper Jacked Bullet)
BI G = Bismuthgeschoss (hardened lead bullet)
Lower line is bullet weight (can't see) but guessing 11,6g = 179gr

Omg thank you fellas so much! I really appreciate the help!
Is there a way to make it shoot the easier to get .323 calibre. .
.318 is virtually impossible to buy anywhere here in Canada, I would love this gun to be my deer rifle someday.
Pretty amazing how ancient my rifle is! I'll try get full pics of it today.

You'd have to rebore it. Much easier and in my opinion better to find the .318 or swag down some .323

93mouse is quite right. The CROWN - crown/N proofmarks show it was smokeless proofed using the then "4000 atm Special proof powder". The standard M88 8x57I steel jacketed bullet weight was 14.6 gramm = 226 grains, service load. The proof date is 213 = February 1913. 125 is a typical Zella -Mehlis proofhouse ledger number, gun number 125 proofed that month. Suhl did not use such ledger numbers then. So the rifle was put together by the Zella-Mehlis guntrade, using an action scrounged from the government factories', likely Erfurt Arsenal, military production. This scrounging was not legal, but happened.
Though it is an 8x57I you may used the downloaded SAAMI specification American "8mm Mauser" 170gr loads. These are designed to be harmless in I-bore rifles. Contrary to popular belief the narrow bore is not very critical here. It is the chamber dimensions, especially a neck and throat area to tight to release a .323" bullet. So Remington at least load their 8mm Mauser cartridges with .321" bullets. If a .323" bullet freely slips in and out of a case fired in your rifle, you may even use European 8x57IS loads.

Well I was digging around my computer and came across a decent picture of my old rifle, when I acquired the rifle I got rid of the ugly magazine and got a proper floorplate. Btw sorry for the thread resurrection!

Hey, Hollowpoint. I just wanted to mention that Tradex has the Woodleigh Weldcore .318I bullets in Canada. They are 200 grain RN SN. Not the greatest design for all hunting, but at least you don't have to draw the .323 down to .318.

There is a way. In Germany, for many years, a 8x57 JS reamer is run into the J chamber. This allows for more expansion at the neck of the cartridge, when pressure is highest. Many military rifles were converted this way, as well as 8x60 versions. The difference in bore size is not that critical, and bore sizes vary considerably. It's all in the neck dimension.
There is a lot of research material on thin, in particular with reference to the 8x60J to JS, and even the weaker actioned mod 88.
Try hitting search, on this very forum, for some reference to this hard fact. As usual, a lot of repeated stuff becomes 'fact' if repeated often enough.
