Does anyone know what company produced this tone control ? I'd guess W& A but this is the only one I've seen with a wood ball behind the tone control to slightly pivot on. It definitely looks factory and its a darn good idea.

There are a few parts that came with this set that are kind of unique.

This other part which I'm guessing is to hold a cymbal on a bass drum hoop to use in conjunction with a clanger is very unusual too. The wishbone shaped part... I've had 4-5 of these cymbal / bass drum cymbal holders and they all are the basically the same design as the one in photos with the clanger and tone control.

Any info would be appreciated.

Thanks in advance.
