This bowl carries a maker's mark 'VK below a crescent' which I initially thought would be for van Kempen, but it doesn't exactly match any of the marks I've seen for him. The closest would be 'VK below a crescent with two dots', but those dots are missing and instead we have a couple of dots within the crescent itself. Is this just a van Kempen mark I haven't seen, or is it for a different maker altogether? The other marks show the bowl was assayed in the Hague in 1861 and is made from first standard silver of 0.934 or better.
Any help much appreciated!
