Hallo Alice en welkom,
My guess is German, the shape looks very much like a model from Nachtmann, but I'm just guessing here.
VSL from this period should be signed, but more importantly, the colour is not corresponding and the cut foot isn't something you'd see usually. VSL have a model 'Teniers' but the base is a little larger and the body less curved.
Give it a bit of time, although you've been doing so already

but maybe somebody has missed your post and can tell you more.
