This looks like mine (from the 30s or so).Recently I went to Ulm Germany and visited noble_house because I have seen they are making a repro of a german 20's / 30's box / aviator / biker coat from Hilbert (old german leather manufacturer, no longer into production).
I have to say it's a very nice repro incl. lining and label. Years ago I had an original one but sadly it is fallen apart due it's age...
