I think you did very well, this was the highest production Modell98 until WWII; Erfurt made enormous numbers this year, but this is about as nice as you will find. I do not think the stock is sanded, actually it is pretty nice and these, while fairly commonly encountered, are hardly ever this nice. Most are interwar reworks or sporter jobs.
Do a picture of the RR?
I think one of the most appealing things about these is the reason behind the large increases in production and the connection to a change in tactical doctrine that necessitated such numbers. While obviously most of these rifles never saw much front line service (most that survive today show interwar service and stayed in German hands, many were obviously destroyed through 1924 and probably figured prominently in destruction totals..) the focus on producing them, and the MG08/15 and P08, was driven in part by the changes in doctrine that the German developed in the middle war period. The creation and reliance upon the Sturmbataillons is a fascinating subject and the numerous photographs of the period with the soldiers sporting grenade sacks, specialized gear and Kar98a should make the 1916-1918 Kar98a part of every collector’s collection.
Plus they look cool!
The Germans might have been terrible at politics and international relationship building, but they sure knew how to make cool uniforms, small arms and were at the top of the field in industrial and military innovation 1890-1933 (I give nothing to the nazi era, the greatness of the German Army had its foundation before those pigs came to power… they squandered and piddled away everything that made Germany a great country).
