Steve and all,
I have an almost identical Navy stock---same steel disc with same Crown/M with number:
8598 no suffix on iron, and Germany marked on butt.
I also have a 1906 Navy commercial rig with matching numbered stock with no disc.
The iron is numbered to gun with #6469.Four digit 1906 Navy commercials are rare.
Sorry no pictures.

Navy stocks are so rare I am not sure of current value.
I was told my matching navy stock adds 50% of the gun's value to the value of the rig.
