Thank you for all the info so far.
As requested a few more pics. My picture taking skills seem to be off tonight. If anyone needs better pics, let me know.
Mag 6 , the one owith the like new crisp wooden bottom, i believe is an original mag, that someone replaced a broken wooden piece. The mag condition is no where new like the wood bottom.
Mag with 4435, this is definitely different colored metal, much duller, darker and greyer, I guess Zamak (whatever that is) seems to be the answer.
How does one tell if a mag has been milled?
Pics are in the same order as previously.
