If you go to the British NRA building at Bisley, you can see the design for an iron running deer target drawn by Landseer on a tablecloth, and the actual iron target in front of the building.
I donated a Ross 22 straight-pull rifle to the museum when I noticed that in their large collection of Ross straight-pull target rifles they were lacking a 22. I had one at home in Canada and I asked them if they would like it, and they said they had heard of the Ross 22 but had never seen one, so when I got home, I mailed them mine. A few yeard later I was in England again and went to Bisley and there it was, my 22 Ross in a cabinet with its big brethren. Quite the place, Bisley, go for a visit, it's not far from London.
