I ended up with this drum, in its case, and I can't seem to find the date range when it was made. It is a family possession, but no one in the family can remember when it was acquired. It is as you can see, a marching snare with the original Ludwig strap. The badge in the picture is supposed to point you to the general time frame of when it was made, but none of the badges I see in the pictures have the word "Ludwig" in a blue oval. Any ideas?
