Himmler was a ring man through and through! Some photos show rings on both hands and multiples as shown here...
There are photos of him wearing his HR. I think he liked 'changing them up'! I don't wear the same ring all the time [except wedding band]..
He probably had plenty of rings [I also remember a photo with a Skull and Snakes ring] .. I think he just liked to wear different rings depending on ? ,,,but he definitely had a HR and did wear it sometimes.. Why not all the time [?] Something we'll never know............cool photo , thanks for posting it........
