Presentation Luger

[jared427]

Wondering if anyone might have a little more information on this? So far I understand that it has Georg Lugers initials on the rear toggle and the serial number 10085 B which also indicates that it was a prototype or presentation piece. The extractor is marked with carregeda. I’m assuming that it went to a Spanish speaking country. The chamber is inlaid with R.S.H 1907 with a 6 inch barrel. I think the gun might be a 1903 going off of Georg Lugers personal Luger serial number 10077B which is a 1903.
Thanks,
Jared
