What is the manufacture date of a Walther P38 pistol with serial number 219331?

No way to answer without a detailed description of all markings, condition, finish, box, papers, accessories, etc.. you may look on the trigger guard near the front on the Lt. side if it is not a ww2 gun it may have the year made there / mine has a 67 E.I. 1967 my ww2 P38 has lots of numbers all over it and letters before each letter = month made and # is the order it is in that run for the month
