When I stopped by Rodger's place 6 months back. The Ariel logo pattern was clean and reproducable (I bought 2 for the boat and 1 for a half hull that hangs in my office), the Commander logo plate was being done as a lost wax model and had some problems where the zinc original was corroded (the copy shared the same flaws).
If anyone is interested in making a new pattern, either a new wood model needs to be produced or an original needs to be cleaned up and repaired...
