I’d prefer either of the two FNs he’s selling. You can depend on them to function properly. The .358? Maybe, maybe not.
Nice stuff for certain. Guy must be getting old, divorced, or married; maybe all three!😛
He's only got one FN, the .257. The other "Commercial" Mauser is a WWI Kar98, originally in 8x57 so, it may or may not feed 7x57. In any event, it is less desirable than the Mexican Mauser the OP was interested in.
