Axel,

The museum is closed, the last I had heard. I am not sure when it is scheduled to reopen. Here is the website: http://www.museedarmes.be/home.htm
It is possible to search for images from at least part of their holdings on line. Although I have catalog numbers for some items that are not possible to pull images for.

Drew,

Wrong museum... Although I have been in contact with researchers at Liege in the past.
You are correct, I should go and visit both of them. Ready to come along? I promise a trip to Birmingham if you do
