Welcome to the forums Mikeinmi
Your wife is awesome for gifting you this Artillery luger
If you get time we would love to see images of the barrel where it meets the action and as many of the serial #'s inside and out as you have time for. There are some highly knowledgeable members here that will be able to tell you much about this gun ... a free appraisal so to speak.
I have no idea why someone would butcher the chamber date but sripples thoughts make good sense. As for the left grip replacement it may have had the dreaded 'million dollar chip' and was replaced thinking it makes the gun more desirable.
An original numbered chipped grip trumps a non-numbered intact replacement grip however.
Again pure speculation as to whether it was safety chipped or not.
The gun is over 100 years old and been used in WW I at least and perhaps WW II ... I hope I look this good at that age.
