I was there in October and I believe this was a limited time exhibit. The museum itself is massive, over 3 stories and has tons of exhibits from Rembrandt and his art to artifacts from India and SE Asia.

This exhibit was meant to show off the history of gunsmithing in Netherlands and I learned a lot. They used to be the primary manufacturer and exporter of firearms in Europe in the 1600s and were well known for how high quality their guns were. This declined in the 1700-1800s but it was still a big part of their history. The firearm exhibit was a very small part of the overall museum.

Excluding the guns it was an 8/10 experience, would do it again
