mauser detachable mag

I'm looking for a GIBBS RIFLE detachable Mauser magazine that can be used for a 22-250 Mauser. i have a 1909 argentine Mauser that was re barreled for a 22-250 heavy barrel. well they just put a one shot follower in it and i want more. i would consider a altered follower if someone has one of them that will work for the 22-250 but i perfer the mag.
