Greetings, all
I'm looking for the Thayer valve for my older Edwards B454. The Gb valve is pretty worn and is in need of replacing. If anyone has one in good condition you'd like to sell, please reach out to me.
Thank you!

You should really get Getzen/ Edwards to check both and get them to spec. Unless something has changed recently, that is a service they provide (for a cost of course).
