Last year, we found an 20mm MG FF/M next to an german field airport in the ground. This airfield is a little sport airfield present days in Hungary. This MG was probably an part of a Schräge Musik from a German Bf 110 G-4 nightfighter. This field used the german Luftwaffe in 1944. october. (Sorry but I took my photos by cellphone)
