Ludwig 1930's Rope Tension Drum ?

[ssoccer]

This drum is a bit of a mystery to me and I hope you experts can help me figure it out. I hope the pictures transmitted. If not, I will try again with a follow-on post. Based on the untampered badge, this would appear to be a 1930's marching drum 15x10" in size. But I cannot find any rope tension snare drums of this sort in 1930's catalogues. There is as you see no rim hardware for the ropes, only drilled holes. At first I thought it might be a 1940's war era drum, but the badge would indicate otherwise. Any thoughts please?

My thought is that the drum was probably made specifically for the army and that's why it's not in the old catalogs....? In other words, it wasn't offered to the public. I dunno...
