Hey Joe,
When you consider that the Germans were tasked with blowing up the wives and children of the trawler sailors, I can understand why they were not willing to take more than 3 times their number of armed men on board, the Germans could have surrendered their arms, rather than offer parole.
Hey Brett, I will bet that the bit of Zeppelin is farm machinery, if it is made of aluminum, then you know you have been taken, all Zepps were made of steel, the farmers in the UK during the war had to use the much weaker aluminum for their farm machinery, because all the iron was taken to make shells, but fear not, if it is aluminum, I will take it off your hands, although I will only be able to pay you half what you paid for it, as aluminum scrap prices are down right now.
Best
Gus
