Re: brazilian mauser 08/34.30
Are you restoring or sporterizing?
If restoring, I'd guess most of the parts are similar to the Brno VZ24. The sights are different than the other Brno contract rifles according to my ref books. You might want to check in on the mausercentral.com forum for more info too...there are quite a few collectors over there that might be more familiar with the Brazilian contract rifles.
If sporterizing, any large-ring Mauser parts will fit the action.
