I found the below web site while surfing over the last week or two and thought I would share it.
The web site is in Danish (I think) and hence completely incomprehensible to me.... But it seems to be a web site for a museum (or museum display) regarding firearms, It covers fireams from the mid-1500s right through the late 1900s, but seems to focus on Scandanavian, Germanic and Dutch firearms (with a dash of some others). Anyways, it's really worth the look even if you (like me) have no idea of what the text is saying, the images are awesome!
Hope you enjoy this site as much as I did.
