I've copied this over to the forum from our Facebook page, hope you don't mind, Brian.
I to find this very sad, I was only talking to him a couple of weeks ago about an article for the magazine about the WWI German submarine cruiser 'Deutchland' (1914) which went to the USA to try and convince the Americans that their activites were peaceful!! Harry was an avid collector of submarine cap badges and he had one (an original I believe) from the German sub which he had photographed together with internet data on the sub.
I also followed this up on the internet but have not found any reference to that particular badge. There may be copies out there so it would be interesting to see what others think or know.
A few years ago I also talked to him about his time as the magazine editor, and we exchanged mags, and only last week I looked at what I believe to be his 'introductory' issue which was soon to be sent to all corners of the world, over 300 copies every quarter!!! As he said, he and his wife used to carry 7 carrier bags to the post office each time the mag went out!
My thoughts go out to his family at this sad time.
