I am guessing the 3 items with the crossed fencing swords are probably the breaches with a cross pin from some of the small breach loading cannon the incindeary may also be a hand thrown device.... hard to say since there is nothing to scale it by.... the grenade launcher has a very stout barrel..... there are some very interesting mortars there of all shapes and sizes looks like an interesting museum complex..... wouldn't mind seeing it someday for myself.... and as for the music I didn't much mind it... I have been subjected to stuff I couldn't stand on other peoples videos tell your relation to keep at it.
