I've never heard of or seen one of these kits before. Interesting hardware.

 
I bought the kit by accident: when I first needed a good kit for a prospectively good band that I started to play with, this was the only one of proper quality available in the nearest shop. I loved its look and sound, so I bought it.
Now I regret that I let it go later (I bought a car for the money I got, shamefully enough) -  I should have kept it just like I kept my Paiste 602 hi-hats back and stored them in a cupboard for 25 years.
As for the Caroline pedal, now I see on the ASBA site how precious and inventive it was, but that time I didn't find it too convenient, I used my good old Premier 250 instead... Now I wish I could try that Caroline again.
