From DNW London,A German Second War Luftwaffe Honour Goblet.
Known as the Ehrenpokal, The Luftaffe honour goblet produced with the material known as Alpaka, awarded to Leutnant Herbert Eichblatt, award date ’23.10.42’. Herbert Eichblatt was a stuka pilot with Stuka Geschwader 2 and was also awarded the German Cross in gold. The goblet is very dark, it appears to have been coated with a form of varnish, which has solidified causing a rough uneven finish to the goblet overall and artificially darkened it, good condition. (I Think it may have been in a fire)
