$350 for a dececent BrazilianMauser is only a dream in Canada
. An all matching Brazilian 1935 or 1908 with matching bayonet, in 95% condition will sell for $850. A minty unissued one can and does go for $1000 if it has all of the accessories and maybe more with an uncracked sling and original target.
If they are in decent condition, they are outstanding shooters. Capable of sub MOA groups.
