There never was a blood oath remeberance medal.....It looks to be clash of designs from several tinnes. To me it is an aged fantasy style fake.
The ribbon is taken from the WWI veteran's Kyffhaeusserbund Medal...Also, just to help out, the proper word for the oath-taking ceremony is "Vereidigung"...happy hunting, friend!
A fantasy piece of poor quality... and in any case, Hitler did not allow his face to appear on medals.
(However, it is worth noting that the "tails" side is actually based on something from the period: The helmet/eagle/hand design was the motif for the day badge of the 1936 Tag der Wehrmacht [Armed Forces Day].)
Thanks a lot for the opinions! Really appreciated!
