Unknown Luger mag?

[Lugerdoc]

Roland, You already have the Danish mag as shown in your photo above. The only mags that I've seen that were correct for the late 42/BYF m&n suffix Portugese PO8s, were blued extruded Schmeisser FXO mags, usually with unnumbered aluminum bottoms and with the serial number later engraved on the spine.
