Also, just above the 1st preliminary German stamp of Imperial Eagle paired with a Crowned S is another Wildmann w/ a Staff on each tube. Then there is another set of preliminary marks on the flats. With the new powders and new fangled steels, tube makers will a little unsure if their tubes would completely pass proof and they were to make up the whole of the lot should the tubes fail along the way. So early on they sent the tubes to the proof facility in mass before they sent them on their merry way.

Cheers,
