I acquired this over the very, very short summer . This is a new example with no marking on the dial and just an arrow for the north and south. Still points north even. This one is not liquid filled at the present and not sure if it ever was or not. The markings on the back are clear but were difficult to photo as they are light. All opinions are always appreciated as I am here to learn. Thank you for looking.
