Online weapons collections that I use.
The Royal Armouries - a very broad collection including ethnographic weapons.

The Royal Collection - primarily European, but with a very fine collection of Indian arms and armour.

The phenomenal Wallace Collection - both European and Oriental/Asian collections.

The Kunsthistorisches Museum in Vienna - seems primarily to have the European weapons digitally catalogued, though the collection has a fair selection of high quality Indo-Persian items.

The V&A Museum - unhelpfully a lot of the collection is not yet photographed, but the items are described in detail, and you can request pictures of anything of interest.

Of course the amazing Metropolitan Museum collection.

Not ethnographic, but perhaps still of interest - the UK National Army Museum.
