On/off valve

Is it a beneficial type?

Almost looks like Brent "Twiek" Crowe's Valve2.

Can you snap a pic with it disassembled?

ill take some different pics, up later tonight or possibly tomorrow

however i think this was a semi common/manufactured, aftermarket on/off

That's a "Reactor" valve by Centerflag. They used different size on/off pins and were of no value whatsoever as far as performance goes.
