WW II Plane Crash Machine Gun
BBC News - Test firing a Spitfire machine gun
"TV historian Dan Snow test fires a machine gun from a WW2 Spitfire which has been recovered from a peat bog in Co Donegal where it had lain buried for 70 years."
This interesting tidbit was provided for the members of a small private forum of which I am a member. Following is all the forum member had to add.
"One of John Browning's great works was dug out of a peat bog after 70 years and test-fired. No one here will be surprised by the result."
