Thanks for the interesting piece of information Lagopus, ...... did not know about the UBoat profile.
Cannons over here too Joe! A famous (over here anyway) Wildfowler called Abel Chapman took his punt gun and outfit to hunt in Spain at the turn of the century (see his book Wild Spain) and they made him register it as a vessel of war which effectively made him part of the Spanish Navy. Punt gunning was not practiced during the war for the fear of being mistaken in profile for a U Boat.
Some years back I had the chance of a 1 1/2" breech loader but it meant a trip all the way to Inverness in Scotland so I passed on it. Something I have since regretted. Lagopus.....
