Chris Chettle from the UK sent me photos of this escape compass I have never seen before.
This escape compass is 15mm wide and only seems to have one big white arrow with a luminous paint tip. The glass has a beveled edge and is flat, not domed. The brass casing looks similar to the other British escape compasses, with a small dimple at the bottom, from the metal turning tool, no doubt. The brass casing has been crimped around the glass cover.
If anyone has more information about this variation, or if you have another type of escape compass that is not yet in my article, please send it over.
