Earthenware tankard with an indistinct mark.

A nicely glazed tankard. The mark is indistinct and may not even be a mark, possibly a glaze reaction that I am seeing as Ev. I could be completely wide of the mark here, but it feels Scandinavian.
Any help appreciated, thank you.

It looks early 20thC to me. Maybe one of the Torquay ware potteries or early Fishley Holland

Thank you Naomi. I agree with you about the age. It does resemble some of the Torquay pieces I've seen. I'll keep digging, thanks again, bless ya

The green might be one of the early Uranium glazes

That sounds interesting, I'll see what I can find out about their earlier stuff, many thanks again.
I once had a Torquay collection of Kingfisher pieces, long gone now, but I would never have connected this with Torquay ware, shows what I know

Early Wetheriggs, maybe?

I came across some similar looking glazes looking at French country pottery a few days back

The shape doesn't seem to shout British pottery somehow.
