WFL aluminum with sticky back drum badge. I would consider this the hardest to find badge since it was a peel and stick transition badge. It was probably used just at the beginning of the war until the one below was put in production. 1940's

I can't confirm the color on this one, but it is from the same era as the two before it. It could just be a yellowed aluminum badge.

1958-1959 Ludwig Keystone Transition badge. These badges have been found on drums from the 1960's. There is no exact date of when they stopped and switched to the next badge - there are cross-over drums.

These were on drum cases, and were never on drums.

Started in 1969 and carried into the late 70's Blue and Olive Badge.

In 1971-‘72 Ludwig also used B & O Badges without Serial Numbers (LVDC) (badge courtesy: O-lugs)

Blue and Olive Cut Badge with rounded corners. This was on a Black Beauty Snare Drum from the late 70's

Started using this late 70's (1979) due to complaintes from the pointy badges above getting caught on things and bending.

An earlier pointy version.
