Question on mag

[romer12]

I have a couple of dark blue luger mages. look similar to the FXO mags, but not so marked. All metal except the plastic base, similar to the FXO. Only markings are:
MADE IN GERMANY on the bottom of spine.
I have always been under the impression anything made in Germany after 1945 was always marked: MADE IN WEST GERMANY. This mag does not show the word 'west'.
Could this be a commercial pre-war mag. ???

The mag seems to be very well made............and in good condition. Thanks JOHN
