The British Crusader AA Mk I is described as having a 2 Pdr AA gun.
I found a couple of sources that say this was actually a Bofors 40mm gun (as this was an AAA unit, this makes sense).

Of course the Bofors did fire a 2 pound round, so perhaps this caused some confusion.
Anyway,in SP the Crusader's AA gun is listed as:
ACC:10 Kill:14 Pen:1/2 Range:40 HE:35 AP:5
The Bofors (unit 64) is listed as:
ACC:14 Kill:15 Pen:1/7 Range:46 HE:35 AP:5
Compare this to the German SP 3.7cm Flak 36*:
ACC:14 Kill:14 Pen:1/6 Range:41 HE:35 AP:5
The Crusader's 40mm Bofors was issued with some AP rounds which had a 2.7" (7cm) penetration at 0 range.
Do you think the Crusader AA MK I should actually have a Bofors?
