That's one actually made by Walther! Have it checked out by a competent gunsmith if/before you do fire it.
yes it is... i’ve looked at it with bore scope and everything and it looks near pristine with no rub marks on the blue or anything
he picked it up D-Day+X in france and it prolly has never seen more than target practice
i would feel less confident in it if it was late war production but i doubt i’ll ever run it
