Rare WW2 German Luftwaffe MG151/15 Rounds

This is a rare set of three inert WW2 Luftwaffe issued MG151/15 cannon rounds. All three rounds are maker marked, dated 1942 to 1943, lot numbes and bear Luftwaffe acceptance stamps. The middle projectile is armour piercing and the two either side are HE rounds with removable fuses. The MG151/15 cannon was developed by Mauser in 1940 and first fitted to the legendary Nazi fighter the Messerschmitt Bf 109. The calibre was increased in 1941 to 20mm and redesignated the MG151/20 making these that much rarer. Included is an even rarer set of original belt links. The MG151 was fitted to many Luftwaffe aircraft including the Junkers Ju 87 dive bomber, Dornier bombers and Fucke-Wulf fighters to name but a few.
