7/18/19 - This is an original Mauser / Walther G43 / K43 manual and spare parts that would fit into the buttstock of these rifles. The manual is in great condition with all pages in tact, although there is normal aging and wear throughout. The paper is tattered and worn - very delicate but in tact. 1944 dated and has black & white images. There are three small parts included (as shown). All original and authentic.
