Hi Dwight,
Take a look at page 334 in Eugene Bender's larger, 2nd. book. He shows a field armourer's wooden tool box with some intact magazines inside...along with many other parts for lugers and the M98 rifle...however...I think this is a 1934 era item...not Imperial.
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
