One of the places I visited was Guernsey. It is owned by the British but it is a small island off the coast of France, west of Normany, past Cherbourg. Guernsey is famous for being the home of Victor Hugo during his exile from France. He lived there for 15 years and it is where he wrote Les Misérables. During WWII, Guernsey was occupied by the Nazis. I arrived there on Sunday the 10th. Just two days after the 70th anniversary of VE Day (Victory in Europe Day).
Near the port, there is La Valette Underground Military Museum. The museum is housed in a converted Nazi fuel depot. Supposedly it is where they stored the fuel for U-Boats. Inside the museum is a collection of Nazi documents, uniforms, badges and other items from the war. They do have a collection of firearms as well, mostly pistols.

They have quite a few older pistols. Some are from the war, others were found or collected and put into the display.
