Although most origional WWII documents were lost. This data came through AAolds Grandfather who was an actual WWII tanker.How much more precise can you get as far as source of data.Although I understand your inquiries on whee you would mount it and all the other arguments.I'm sure AAolds will dig deeper into this topic .These threads are meant to promote intellectual debates and conversations.Some seem to feel better by trying to discredit or insult others but we do not get our kicks that way. Trying to make someone else feel or sound bad is not what makes us feel better.It only shows one's own true ignorance.For all who gave intelligent replies and raised genuine concerns ,thank you and
