Rectangular Pot Green Glazed Interior

Something I inherited I think, I've had it a long time anyway. I love it, and it sits on my windowsill.
I have been looking for some information on it (no mark).... it's quite old but I'm hoping someone will spot it straight away.

Briglin? German?....or way off?

Far Eastern ikebana vase is also possible

oh...I didn't think about that. I've had a quick look and I see exactly what you mean.
Thanks Naomi, I'll have a search and see what comes up.

Hi Stardust

It has a glaze that reminds me Andre Loret sculpted head I posted a while back (link below), it also has a similar clay. No idea if it's linked but it does remind me.

Thanks Mordeep, does look very similar.
