Swede, thanks that you took the time to look into that! Your stock holds the information I did not have. I had the theory that only the s# 1-5000 Oberndorf made rifles would have the Mauser wrist crown. A crown with an arched top and bottom base. Your stock of a much higher s# proofed my theory wrong. I believe we both can agree that most likely all m/96 stocks that have been made by Mauser Oberndorf have that crown? Possible even the m/94's?
However due to the time in service and several rebuilds the crown got dressed out when reworking the stock. I have an old Oberndorf stock which shows besides several crown marks two (ghost) marks I can not identify anymore.
You mentioned that the second crown is CG.
Over the years collecting Swedish Mauser's I have noticed a change in fonts and slight variations in regard to the CG crown mark and digits. However the crown mark always showed a straight base. A straight top and base line.
In regard of Mauser made parts or rifles in the time from 1895 to 1900 when Mauser provided rifles and parts the crown mark as well the fonts have not changed to my knowledge.
The crown mark on the wrist of the rifle in the picture are both CG the stock is CG even so it is installed on a Mauser made m/96. During rebuild of the rifle the Mauser stock was removed and replaced by a handguard/stock set made by CG matched to the Mauser s#. It is an early rebuild the full s# was stamped in the stock set. Even the buttplate was numbered to the rifle holding a CG crown mark. My point is the CG crown mark in the picture and the second crown in your picture are different.
The handguard and the stock have been inspected after production. If accepted by the inspector a crown mark was stamped on the part. The crown approval stamp on the handguard is on the inside at the front end pointing to the front sight, the crown approval stamp on the stock is on the outside at the wrist. When the stock set was used for a new rifle and the rifle was sighted and shot a second crown mark as acceptance was stamped as second crown after the first crown on the stock. The Swedish did it that way so did Mauser Oberndorf. For me it is hard to believe that Mauser built a rifle for Sweden without sighting it in and test firing it? They way I understand your comment is that the rifle was built at Mauser then sent to Sweden and received the approval stamp for sighting and shooting the rifle in Sweden?
