This rune is the Opfer rune. The name means ‘offer’ and relates to the sacrifice or offering.
This rune is clearly connected to the Wolfsangle but lies horizontally and without the central stave. The rune also rotates anti clockwise, whereas the Eif rune is the mirror image.
In Volkish Germany this rune was used as a rune of remembrance – when the volk remembered and honoured our ancestors and the movement’s martyrs.
In these pictures we see the Opfer rune in use – the Opfer rune upon a swastika flag at a remembrance rally and on this ‘tinnie’ badge – as a reward for a charity donation.
