Armstrong was a very interesting fellow all round. His house was the first to be lit by hydro-electric power which he generated himself from the lake behind his home at Cragside. I think it was the first to have an internal telephone system too. He patented a very successful hydraulic crane which was demonstated to buyers by one of his workmen called Jack who was very adept in its use. From that we got 'Hydraulic Jack'; a word in common usage today. Just a little bit of useless information as you never know when it may come in useful.
Tim, yes that's the one; the 'Vanguard'; a single barrel centre hammer gun. I used to see a lot of them around but haven't come across one in a long time. Lagopus.....
