Peruvian crested M1891 Argentine carbine

[Anzac15]

I need some info here!
Last Saturday I found this M1891 Argentine carbine at a flea market. I was just about to walk by it, as I already have two, but I just can't pass up a Mauser carbine. I pick it up, and lo and behold, instead of the Argentine crest, I see a Peruvian crest.
While I'm thinking 'well that's different', I knew that Peru received quite a few '91 rifles around 1901 (IIRC) and that some were converted to 'carbines' for the Peruvian navy in the 1930s. The majority of these rifles and carbines being updated with the 'lange vizier' rear sight for the newer 'spitzer' cartridge.
So I get it home, and start to try to research this example. As it turns out, I cannot find ONE picture/photo/ of a Peruvian crested Argentine M91 carbine. The only search results I get are the modified M91 naval carbines with lange vizier sight. Not only can I not find a picture, I cannot find any reference to a Peruvian crested Argentine M91 carbine. Zip, zero, nada. Ball's MMRotW doesn't even reference this example, only the aforementioned converted naval carbine.
This example was manufactured by DWM Berlin. Barrel, receiver, and number on the butt match. Bolt is a mismatch, which is par for the course on Peruvians.
I cannot help but think this is, well, pretty damned rare. Is there anyone out there that has seen a Peruvian crested M91 carbine like this? Looking forward to any thoughts.

I have learned never to assume anything when it comes to South American contract Mauser's. Contracts weren't exactly set in stone, they changed when governments were deposed, or European wars interrupted the flow and needs changed during the interim. The Mauser company itself changed hands several times, plus Belgium, Portugal, and Spain all taking a piece of the action selling south of the US border. A few hundred special order carbines here and there would not be unexpected. All Mauser carbines are rare, and as they were the most in demand by US collectors many were in Bubba hands back in the day. Figure this was imported 60 or more years ago, records are likely nonexistent in Peru, or Germany. The variations of contract Mauser's fill entire books without getting to all of them. Mauser, or FN would make their top customers whatever they wanted, however they wanted it, in whatever quantity required, whenever they wanted it ( so long as a world war or two didn't get in the way)

Definitely a rare bird. I have a ton of Argentine carbines and a few Peruvian 1891's and 1909' battle rifles. But, never seen an 1891 Peruvian carbine before. Hmmmm, maybe once but as I recall it had the lange vizier rear sight. But, that could have been a 1909. Regardless, nice snatch especially with an intact Peruvian crest albeit lightly struck. I think I would have jumped on this one too...
