On the buttplate tang, the "32" is a regimental number, the "L" almost certainly stands for Landwehr, and the "R" would be Regiment. The "W" I'm not familiar with but my knowledge of Imperial German military markings comes from my prior collecting days of WWI-era German field gear. You'll notice the "W" is in sort of an italicized form which could be quite informative. For example, during WWI, there was a regular army 120th Infantry Regiment out of Stuttgart that marked their gear with an "R.120". The 120th Reserve Infantry Regiment (my uncle Hans' unit) would have been RIR120 sometimes with the "RIR" being italicized, or just an italicized R. However, Imperial German equipment/weapons marking could be somewhat creative and did not not always adhere to the standards (shocking, eh?). As for the Landwehr, they were the third-tier units. You had your regular army units, then then reservists, and then the Landwehr who aged out of both the regular army and the reservists and basically stood guard at sausage factories, or schnapps distilleries and the like. Reserve units, however, being considered somewhat expendable, saw tremendous action during WWI and took stunning losses in places like Verdun, the Somme, Flanders, Russia, Poland, etc. The 6C on the buttplate...no idea. That might just be a rack number. The "64"...perhaps an assembly number since I see it in at least two places?
