Which mag?

Howdy folks new to German firearms, but not firearms at all. I've been dabbling in them for about 25 years. I did recently pick up my first Walther AC43 P38 and am slightly confused as to which magazines are correct for my pistol. It's in the b block, so are P.38 Eagle 359 or P.38v Eagle 359 magazines correct for my build? Thanks to all, I'm a newbie here but if you need US firearms or edged weapons help feel free!

Best regards
