Gentlemen, yesterday on eBay I procured the red eagle pin, regularly (and incorrectly) referred to in the literature as the Pomaska emblem (after the 6./JG 26 Staffelkapitän, Hptm. Alfred Pomaska, KIA during the Battle of France in May/June 1940). The emblem itself was sported on a number of the 5./JG 51 Bf 109 E aircraft in the autumn of 1940, but its exact origins remained unknown to this day. Here is the still valid link to the eBay auction in question http://www.ebay.de/itm/261146740102?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2648#ht_500wt_1414 . When the said pin is delivered to me, I will try to post the close-up of it. I would be much obliged if someone could shed some light on the emblem origins.
