I have a 15 inch and a 14 inch.

both have the same badge but the 15 has some damage.

I'm assuming the throw off has been replaced on the 15.

I'm very unfamiliar with these Ludwig badges can someone date them?

The 15 came with Ludwig snares wires and the 14 came with plastic ended snare wires that had a pat. number on them. I'm switched those wires with Ludwig wires from my jazz festival.

unfortunately their both

any knowledge would be appreciated!
