Hi I'm new
i have a Winchester WW2 Garand that was given to me by my Dad when he passed
i always thought it was all original
its in the 1,6xx,xxx (1945)
it's in excellent condition
the stock stamp Mark is
WRA/WB in a Box I can't find any other stamping
I was told this is not the correct stamp for a 1945 piece. I'm puzzled as Dad was not a collector and had this put away as long as I can remember
are there exceptions to info I have been told.
I don't know how to post photos but will if I can figure out how to.

Thanks so much for any iinfo.
