Ken,
You should be able to find a decent original magazine (nickle plated, wooden bottom, for around $ 50-75) for your nice WWI luger at local gun shows in Oregon...or you might try posting a Want To Buy add in the Classifieds section at the bottom of the Luger Forum main menu. Keep an eye on e-Bay as well...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
