Yes. The condition of the one that I saw was not as nice as the OP's, but very respectable. It is my understanding that it came out of an Orange Lodge in Ulster.
Mine was in rough shape, bore was washed out. But I baught as a curiosity and I knew Smellie didn't have one so I "accidentally" left it at his house!
They are very rare, according to history most of the 10,000 ordered were confiscated by the British coast guard. I've only found 4 others floating around on various forums. Including the one I had they were all under serial number 500 and 3 of them were only like 50 numbers apart.
