wooden sewing box... i guess

I found this in a storage unit and am interested to know more about when and where it was made, and value.  I am thinking it is a sewing box, but would be interested in know if I am correct on that as well. I don't know much about it.  There is a neat handwritten letter that came inside it... don't know if it is connected with its history or not.  But I am uploading a pic of the letter that you can read. It is in good shape except for one hinge on the top lid... the screws have come out.  The hinge is still there.
