Not a gun, but related
 

Well, today I got this Mauser 1891 bayonet for u$s40 (pretty cheap).

The next Mauser-related accesory will be the rifle grenade launcher, for u$s17,50 (I didn´t buy it today, not enough cash).

Smoky Mountain Knife Works had them back in the late 90's for twenty bucks apiece. (The grip was difference though.) Two of my friends got them, I passed. I kind of regret it now.

That's a nice bayonet. I do love the longer, WWI-era bayonets.

Wow! That would actually be incredibly rare in North America, the Argentine crest was scrubbed off all the ones that were exported. Great find!
