Todd,,, well,,, I'm wrong [and glad!]...... I thought they were always around. but not even close!

OK, started in 1918,,,, and by 1935 they got absorbed by the SA and the Veterans Bund.... But,,a short reemergence in 1951 but only a year or 2.. and thats it!
German veterans continued to like the emblem and unofficially used it for years.
.
They style of the ring in my opinion is not an early one.. More like 1940s / 1950s.. Try and make those big shots...

Todd, can you see a joining / sizing seam at the rear of band?
