Another eBay pickup, unfortunately not working.
Interestingly there are two date code marks, the arrow and the triangle. What are the reasons for that?
Given the serial number I'm going with the arrow and 1937. The case is clearly a Lone Eagle. The indices on the subdial are a bit of a mystery. I don't see non-numbers in '36 or '38 and we don't have '37 adverts with a Lone Eagle.
Adverts show a ladder band, obviously mine isn't correct but I think it looks ok.
So, 1937 Lone Eagle?
