There was something very strange about that map! Symbols were way too small and barely visible on the map. 134 was on a work of fiction.
Apparently they refused to pay what Dave Peel quoted for a remap. They prefer to stay in the 1980s...
they should have asked me!
either way, reckon they created the 1:10 version in OCAD and retained 1:15k dimensions rather than blowing up to 1:10 for printing: narrow gullies were effectively invisible; also didn't smooth/check LIDAR contours
