Unusual studio lidded handled pot, medieval seal

I’m thinking this is amateur piece - it’s fairly heavy.
Stoneware, nice speckled greenish grey glaze.
Applied seal with dragon, shield and motto.
Or is it something ?

Looks something like : m DAT th Deus Ino Remembrum
Maybe a town motto? Looks old. German or Belgium?

I think because it’s not particularly well potted I thought amateur made but it could be proper old.
It might take a while tracking down. Not a glaze I know from old pots I’ve dug up in Britain. Seal is like the Tudor age German pieces.

All though the base and seal are interesting, my head is telling me it's old but not that old. Really old pieces would be covered in use, chips and damage. Handles and a lid would just not survive in that condition perfect if it were old. So Head telling me it's late 19th or first half of C20th because of base.

I’ve seen Tudor pieces come out of the Thames in pretty amazing condition but I know that’s an unusual situation. I’ve handled a lot of pieces of that age but this is a bit out of my experience.
Maybe like you suggest it’s an old pot looking like something much older. I find it so hard to know how to deal with uncertain pots like this! Thank you, you’re all so helpful.

It's one to keep looking for, may take years. Try and find/ID that seal and motto. Could it be linked to a monastery.
