Hello, got a couple questions on a kar98a I've had a while. On the top of the buttplate there is 9. U., is this a unit or regimental marking? If so, does anyone know what? Also when I bought it, it had what the guy told me is the original sling. Its in excellent codition and marked Robert Larsen Berlin SW68. Could this be a correct sling for this rifle? The rifle is Erfurt 1914, in excellent condition, and everything matches but the stacking hook. Any ideas on value of this rifle? Thanks in advance for any info. Gunnut.
