Albatross ammo chute

[Olson]

I am building a 1/4 scale Albatross D-V (Proctor kit) which will be finished to represent the "Edelweiss" of Uffz Paul Beaumer. The best photo I have of this aircraft is from the Ferko collection which shows a dome shaped cover located where the ammo belt chute (feed or discharge?) is adjacent the side of the m.g., instead of the twisted rectangular chute usually seen (and provided for in the kit). I presume it is a stamped sheet metal part. My question is whether this is a field or factory modification applied to all four chutes on both m.g.'s as the photo is taken from and therefore only shows the port side. If present on both feed belt chutes and both discharge belt chutes can I assume all four are the same shape and size. Sorry for such a big question regarding such a small matter........John
