Re: A few questions on a 8BA
I think you're right, Mart. When I look at the valve on the right, I think I can just see a glint of the valve stem, and it looks like a regular stem. I think he is seeing the rotator mechanism.
I think that the later valves are quite bit cheaper than the "mushroom" pieces, so I would check prices on the later assemblies; you might be pleasantly surprised.
