Recently I was admiring John Furnival's favourite map on Acejet: A modern admiralty map and I was reminded of my favourite map, which was given to me when I was 12 by my Grandad. I was given three Admiralty Survey maps engraved by Davies and Company, from the 1920 edition. All black and white bar the markings my grandad made on them during his Navy days. I have always thought the numbers radiating from the large circles were very graphic and have been meaning to frame one for years. Maybe John and Richard have inspired me.
