Mauro,
Not sure if you saw this 1902 Cartridge counter Mauser luger for sale or not :
http://www.gunsamerica.com/guns/976381830.htm
I believe the seller is a LF member named Leon Y.; who showed us some of his really nice Russian lugers a few weeks back...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
