Hello Bob, and wecome...
If you switch to the "Artillery" luger discussion section and click on page 3 of the discussion threads, you will find a discussion from last summer titled "TM-08 Leather Carrier Question".
Cannot be sure, but from the photos I would venture a guess and say the holster you have may well be a reproduction and not from the 1915-20's time frame...brass looks a little to shiney and the leather does not have much of any aged, patina look...
Does your holster have any maker's stamping and date...?
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
