Boer Mauser - Mystery markings

[Surpmil]

First step would be to determine if it actually is a Boer rifle - I referred to it as such without checking - I see no Boer markings and can't recall the exact details of the serial ranges, but the info is online.

There were some rifles from Boer orders that were never delivered and some of those were later sold to Chile IIRC.

If this is a Boer rifle, it is possible the stock was already changed by someone, but I would make very sure before changing anything. The stock may well be original and the repairs may even be of that era; you might want to post some photos.

If you have obviously very old repairs, and repairs that are not of a military standard of quality (and therefore probably not done in Chilean service), then you may have repairs that support a Boer provenance.

Start with the hard data on the serial numbers I'd suggest.
