Yes I do have them.
I hid them in my cockpit as I'm currently on the hard in a boatyard and noticed a couple shady fellows with an interest in bronze.
I think there is 5-1-1/2" valves and 2-3/4" valves.
They were in good working order.
Regarding a value I would have been very happy to pay $50 each plus shipping for the replacement cones alone for use as a spare.
So, I guess $50 plus shipping each should be my price.
They are in good shape but still I will only sell them "as is".
