hamelner töpferei

Very crisply made small beaker/cup with mottled texture matte green glaze, red earthenware ground is exposed at rim and base. Impressed number and mark, with further possible brown glaze type mark on top.
Looks Scandinavian....?

Looks like it's got an impressed leaf mark, which I think maybe Swedish?

Thanks Naomi, that narrows it down a bit, will do some of research in the morning...
