Very nice sword, Wayne! At first, I was hoping I could get an 'RN' sword for my occupation (registered nurse)...sorry, bad pun!
It is great that you can have a piece in your collection that represents your own past occupation. In regards to fighting blades, I had wondered about this myself in the past until i heard early accounts of coastguard patrols in the 19th c. running into smugglers, pirates and, of course, occasionally being used for paramilitary ops. I particularly like the fouled anchor under crown emblem. Nice find!
