Small Ink Bottles or Brush Washers. Imp. Mark.

Two little pots by the same maker. The marks were either only lightly impressed or have worn down over time. I've highlighted them as much as possible with flour.

We’ve had it before but not managed to ID it

There's a coincidence I didn't expect. The mark you linked to is indeed the same but the decoration on the pot itself is in the style of the wax-resist pot I posted for i.d. directly after posting this request.
So, it seems that these little pots and my wax-resist pot are all from the same maker.
