congratulations Fred, very well done
Like you I had assumed it was an un-Registered design - well at least I got the trade-mark right in the end.
It is an attractive repeating pattern, and although the foot does have that crack, it's not overly obvious and doesn't spoil the appearance. As I mentioned, the design appearing under the foot is a very nice touch, and shows the trouble they went to in making their moulds.
Anyway, thanks again for all your hunting, and if you would like this piece do let me know and I can post on to you.
