Identification of Haspano 20mm canon part. (2 Viewers)

[Milkcup1986]

Hi .
Whilst dog walking yesterday in a wood where a WW2 Spitfire crashed , I picked up an item that was partially covered by earth and leaves. It still had a bullet wedged in it so I know that it is from a gun.The bullet is 20mm so I can only think it is from one of the two Hispano canons in each wing . Can any one help in identifying it please.? I've seen items that resemble it but they are not exactly the same. Could it be the magazine cowling ?.
Kind regards Danny

Looks like part of a feed chute.
