Unfortunately, there's not a ton of resources out there, but there is one very good book that I'm aware of: FN Mauser Rifles: Arming Belgium and the World by Anthony Vanderlinden. This is what I've been referencing.
Looks like a Belgian 1889 variant of some sort. More photos and better photos would help, specifically those that show marking clearly. I'd like to see proof marks on the barrel/receiver too, which may be under the woodline and require removal of the stock.
FN Mauser Rifles : Arming Belgium and the World and Mauser Military Rifles of the World are really the two best resources on Mauser rifles, specifically Belgian models. I've got both and can reference them to try to figure out what specifically you've got. It's almost certainly a sporterized military rifle.
This is a Peruvian Model 1935 Mauser rifle. Prior to the adoption of this rifle, Peru had largely been using Mauser Model 1909 rifles, in effect a Gew. 98 export model, and Model 1891 Mauser rifles, which were in nearly identical to the Argentine 1891 rifles. They were purchased by Peru due to the inability for the Argentines to pay for all the rifles they had contracted. Peru, like other South American nations, had been working to modernize their military in the early 20th century to compete with its neighbors and gain more power in the region. During the early 30's they would place a contract for roughly 5000 VZ 24 short rifles, but nearly all of these would be sent to Bolivia for use in the Chaco War. During the late 30's trials were conducted for a modern replacement rifle. CZ, Mauser and FN would all enter these trials, but ultimately the FN entry would be selected.
Though based on the FN 1930 rifle commercially offered by FN at the time, the Peruvian 1935 would be drastically different after input from Peruvian officials. The charger bridge would be extended, the safety flag would be reversed, the bolt would have a half flat knob with checkering, the trigger face would be checkered, the buttplate would be ribbed, and a 180 degree swiveling rear sling mount would be designed for the rifle. This design would be used by FN on their FAL rifle nearly 20 years later. 30,000 of these short rifles would be purchased from FN and an unspecified number of carbines along with short and long export bayonets designed specifically for these rifles. These rifles would be used throughout the WWII period, and specifically in the 1941 Ecuadorian-Peruvian War. During the 1950s, Peru would work with FN to convert roughly 24,000 of these rifles to fire cheap and plentiful US .30-06 surplus ammunition. Because of this, rifles still in their original 7.65 Argentine cartridge are much less common to find. As late as the 2000s, a program to convert some of these rifles in stores to sniper rifles was considered but ultimately dropped due to it not being cost effective.
This particular rifle was made in 1935 based on the Belgian date code (*N) in the proof mark. The 1935 rifles have the Peruvian Coat of Arms, which Wikipedia can describe much better than I can. Like nearly every Mauser rifle made at FN, they're marked as such on the side rail. On the righthand side of the receiver they're marked "Modelo 1935".
As per the usual, I probably screwed something up so please tell me. My reference for this information was largely from FN Mauser Rifles: Arming Belgium and the World by Anthony Vanderlinden. It's an excellent book on FN Mauser production and goes into a lot of detail on nearly every FN contract Mauser rifle out there.
