Two stage tail cap for an L4?

[pangris1]

Greetings, all. I found a two stage tail cap I bought for an L4 a couple years ago, but never got around to buying the L4.

It is an aftermarket unit manufacturer had a surfer logo, and if I recall they were out of hawaii.

Any idea of what this is properly called, and what it is worth?

Thanks!
