Very Nice! I also own an 1891 Argentine Mauser in 7.65x53. It belonged to my grandfather who sporterized it. It shoots like a champ, and puts a nice hole in whatever I'm shooting at, with 187 gr. mil surp FMJ ammo. The stripper clips help.
I would like to consider options and update the stock or refinish it and bring it into the 21st century.
It looks like you have a great one. Gotta love those Mausers!
