Transcript for Jim Smith - compass cards
The man who used to paint the compass cards, his name was Eric Brassie and he was actually a fine art artist who’d paint the compass cards which came from Mica which was mined in Africa, believe it or not. He’d split it, rub it down, paint it, then he would actually hand paint the compass cards for these compasses that John Rimmer made which went on, again, the biggest ships at the time in the world. He was a lovely man and his precision... He was the only man we knew who could paint a compass card upside down and backwards because in the fishing trawlers you see, it comes down mirrors. So to get a proper reading, or even on the war ships it comes down in mirrors, and then it eventually reads straight for them but it has to be prismatically upside down.
