I have a HSC serial # 804753 & original holster left to me by my father. It has all of the traditional markings such as 'Mauser-Werke AG...'. However, everything I have read talks about 'letters' under the eagle on the trigger guard, and the eagle at the end of the barrel. Mine has the eagles - but no letters underneath. This pistol & holster are in mint condition. Any comments on how this one would differ from the others? Also - is there a long shot of being able to tell what German officer may have been issued this particular serial number? Thanks for any help!
