German 37mm ammo capacity?

[stugumby]

or perhaps i should have said? on the 37mm stuka pod there are 2 projections that have to be feed or clip ejection as it is on both guns and on both sides of the pod. So, if it only has 12 shots is it a dual feed gun or did the clip go all the way thru and stop on the other side, kind of like a hotchkiss mg? I know the 37mm ground gun was fed from shells placed on a stripper clip type of insert.
