Small arms fire and Paddy Finucane

[Jon]

The veteran Battle of Britain fighter pilot F/O Paddy Finucane was shot down by small arms fire on July 15th 1942 when passing over a beach near Pointe Du Touquet....almost home.

Do we know who or what shot him down, a single soldier with a rifle, an MG42 or maybe a submachinegun and a lucky hit ?

Also are their any reports of single soldiers bringing down an aircraft by themself with a light weapon ?
