Hi Mike,
Your friend really has a treasure and one is he wisely keeping.
Is there a family connection at all...some one in the family that served in the Great War ?
Value of lugers have been really going up. The Folks at Simpson's have a similar 1918 rig for sale for just under $ 6K.

Does your friend's stock (iron part) have a number that matches the gun's serial number ? That is what is meant by "matching stock".
Regards,
Pete...
