Reed valve identification

Does anyone know who the manufacturer was? If it’s worth keeping I need new reed petals for it.

That's a pyramid reed valve. I haven't seen one in years!

Is it something I should keep on the bike with new petals or ditch it for something else?

I would give it a try before you go out and buy vforce 3 reeds. I personally like an oem reed cage with boyesen dual stage power reeds on oem cylinders. They aren't super expensive and they last for a long time.

I ran boyesen on a stock cage in my 86 iirc, for the price of the reeds ($50) I’ll give it a shot, thanks!
