Well, these look nice.
The first one is a spanish model 1943 mauser with bayonet. Note that the bayonet is the same one that they cut John Rambo with in the first movie when he is tortured in vietnam.
The second one looks like a nice Gew98b, some sort of upgraded Gew98 done in the 1920's Export model mauser, cant tell the country without seeing the crest, many possibilities although not in the calibre, to lazy to check all of the hundreds of models of mauser in my books to find out for you. Edit: probably a turkish model 1903 mauser. What little that i see on the crest seems turkish, the calibre also is correct.
The third one looks like a mid production K98k.
All 3 look good to me.
All rifles of this era should have a used look, they went through a war and over 70 years of lifespan.
