Phew, I can relax!
You did not look at a Hyacinth Museum but at the Regional Museum in Lisse where the whole collection of a Swiss friend of mine ended up, after she passed away in the year 2000.
As it was, she had next to no Dutch bulb vases (she found them too simple) and very little English (apart from the few I brought her).
You are looking at a lot of French bulb vases here, quite a few Scandinavian and German and then the odd one from other countries.
I am involved in placing half of this collection in another museum right now for a temporarily exhibition. Only last week I packed both these vases you looked at, in one museum and unpacked them in the other and I can tell you that yours is not like either of them.
If you could handle them like I do at the moment, you'd see the difference as well.
Rest assured, as soon as I find out more about yours, I'll let you know. Just don't give them away in the meantime!
