This is a nice all original Spanish Model 1893 Mauser rifle chambered in 7x57mm Mauser. This rifle is in all original condition. It appears to be all matching, but the number on the bolt is very hard to read. The original crest on the receiver is still present. The bore is a little dark, but has strong rifling and is overall in good shape. The rear sight slider is missing as is the cleaning rod.
If I had to guess, I would say this rifle could very well be a Spanish American War trophy. Of course, it's impossible to say for sure. However, this rifle will make a great place holder for your Spanish American collection!
