Aplogies in advance for the minutiae.
The Hearn pattern cast iron base plug is normally associated with the Nos 23 Marks II & III. The Patent just predates the No 23 Mk II so the use of the base plug on a Mark I shouldn't be a big surprise but I believe this is the only one I have seen. Anyone interested in these trivia have any comments please?
