Guest,
The easy part is the date...kind of. Yours dates between 1943 and 1948. World War Two got in the way of real good record keeping.
The hard part is the value. It
might be worth little or a lot more depending on the condition. Please read the following post and get back with a GOOD description or better yet photos.
