My First Mauser K98 BCD 42 Russian Capture

[2k05gt]

This is my First Mauser, Even though it's a Russian Capture I have grown fond of it. Not much to say really, numbers don't match, the stock is nice and it shoots great. I am not sure what the zig zag mark is just above the 42 on the receiver and there are a few other marking I am not sure of. I do know it was made in 1942 at the Gustloff-Werke factory in Weimar Germany.
