For your consideration are two, anti-aircraft 40mm MK2 AP-T dummy rounds used in the Bofors 40 mm Automatic Gun L/60 from 1944 and 1945 and one 90mm M71 spent shell casing from the 1960s. The Swedish armaments manufacturer AB Bofors created the Bofors 40 mm Automatic Gun L/60, also known as the Bofors gun, as an anti-aircraft auto cannon in the 1930s. The weapon was intended to be an intermediate anti-aircraft weapon, bridging the gap between slow firing, long range, high caliber anti-aircraft guns and fast firing, close range, small caliber anti-aircraft guns. These dummy rounds feature their original brass casings and a blue painted steel slug at the top. The bottoms of the brass casings are marked with lot numbers, the type of shell (40MM MK2) and a date when they were manufactured. One is marked reading, "G.B. 3-44 / Lot No. 196 / 40 M.M. MK2", while the other is marked reading, "1-45 / Lot No. 1618 / 40 MM MK2". The 90mm M71 spend shell casing was used in 90mm guns against personnel and vehicles. No marks on the bottom can be seen from the layer of rust covering the bottom. They show good condition overall with slight wear present from their age and use over the years, but no major signs of damage is noted. The dummy rounds measure 2 3/8" L x 2 3/8" W x 17 5/8" H, while the spent 90mm M71 shell casing measures 5 1/8" L x 5 1/8" W x 23 5/8" H. The three pieces have a collective weight of 16 pounds and 14 ounces.
