Armoury Military Museum, Trondheim, Norway.

[Alan1]

If visiting Norway, the Military Museum at Trondheim is worth a look.
Located in the Nidarosdomen Cathedral complex it has three stories and illustrates the military history of Norway from Viking heritage to the present day.
It has particularly good coverage of the Norwegian Resistance of the Second World War, the bravery and stubborn actions of a number of quite extraordinary people are well illustrated.
A small number of guns and ammunition displays, including several field and siege guns are included.
Some pics herewith, when I've worked out how to transfer from my mobile to this site.

Not having a six year old grandchild to help, I am still struggling with transferring pics from my magic i-phone to this medium. I shall persist.
Meanwhile, if in Norway, another museum that you should not miss visiting is the Lofoten Krigsminnemuseum at Svolvaer. This started as one man's personal collection but has expanded into a very significant historical resource housed in a large building very close to the docks.
It is impressive, covering a wide range of German uniforms and equipment as well as Norwegian, British and other Allied items of the time.
Whilst the original owner was very well placed to hoard what the occupying forces left behind, the Museum has at least some tacit approval from the Norwegian Government, who clearly recognise the importance of their nation's historical heritage, unlike, I have to say, successive Governments of the United Kingdom.
As well as kit left behind, the collection has expanded into other preservation projects, including heavy chain links from the wreck of the Tirpitz, and even a replica of Hermann Goering's heavily decorated Luger pistol.
Pics, as above, as and when.
