2 Post WW2 Bofors rounds

[Gspragge]

Drill round and a breakup round. The breakup must have had some kind of
filling ? It weighs nothing without any.
Break up marked; 40mmG, BREAK - UP MK 10/2, 4/74 LOT 169.
base plate; SX15SA

Yes, the break up projectile would be ballasted with granules ( possibly metal punchings ) to simulate the weight of a normal projectile. They were intended to allow the testing of guns on short ranges since the small granules would lose their energy quickly.

I’ve seen them being fired at very low flying Canberra aircraft at Larkhill, they went a very short distance, probably not much more that 100 yards
