Thank you for sharing that Bruce, I went back through my emails from Geoff... I ordered the same set that Jack had in one of his videos, which included what Geoff called the “Rolls Royce” models. They were a 4” feed water tower in nickel and a 3” chuff pot. He did offer me a 4” chuff pot for $120 AUD more, but I thought the size of the 3” looked and sounded great with the 50... Did anyone end up with a 4” chuff pot?
Yes, the one I commissioned was a 4"Od barrel.
