I sold my old signal lantern at an auction here in Australia and it more than paid for the upgrade I got in the mail this week.
It is dated 1941 and is complete with case, two tins for candle, lens tin with two each of clear, red and green lenses, and combination spanner/wax scraper.
There is though one large internal cradle for some item, could this be for a spare candle shaft? Another very small internal restraint just below the top of the case must have must held something but not sure what.
