Hi,
Tried to photograph my Suhl-crown, but got stuck on the limited close-up quality of my camera. So I reworked the illustration so that it matches the real crown a bit more exactly:
The specifics of the post-war crown are that the horizontal marks of the N stick inside quite a bit, as opposed to the old crown-N. Also the Suhl crown is more elongated as opposed to the old crown. This also makes the Suhl crown-N slightly longer. (5mm total length from tip of the crown's cross to the horizonal bottom line of the N).
