Help To Identify Shell Case 40mm L/60 - General Ammunition Discussion - International Ammunition Association Web Forum

Would anybody be able to help me identify or point me in the right direction of identifying a shell case. This is something that i have brought and am now trying to research to find out its history. It is a 40mm L/60 (Brass) NP 13/52 (I am guessing the 52 is 1952) B with an arrow going throw the B (I am guessing this means Bofors maybe the logo) B5215 The case / cartridge is roughly 12" in length I have attached a photo if it helps.
