I have a custom rifle built on a small ring Mauser action stamped M98. What I understand from the gunsmith who built the rifle, the M98 small ring Mausers were always made to be sporting rifles, and never used in the military. I would be interested if anybody can decipher any more info based on the stamp marks I found under the scope mounts.
It appears to have two dates 1915 and 1920?, and a crown logo with ERIURT stamped on it and a 57?

Any history and information on this rifle action would be of interest?

Made in Erfurt Germany in 1915. The #57 is the serial number.
