Aluminum fairings...OH NO!!!!
Those fairings are aluminium Paulo
This one really bugs me!!!! As far as I can tell, NO German built Albatros D ever had aluminum fairings! I've looked, believe me, I can't find a single photo where you can see the wood grain that the fairings are aluminum. I think this is a complete fallacy that is a carry over from artwork of the plane. Unless you see it in war time photos, you just can't be sure. Jim Miller was the first person I heard this idea from. At the time he thought some of them were wood. But as I said, after looking, I'm positive they all are wood. Jim also has a square footstep too and he'll be the first to tell you that's wrong.
I've got good photos at home and I'll be glad to post them tonight. But for now, here is a photo of Voss' plane. Tell me if you see aluminum fairings, painted or otherwise-

Here are a few others of Albatros Ds, all essentially the same in this area-




You just wouldn't know or even question it unless you had a reason to look. Jim had mentioned it to me while I was working on profiles of the D.V. When I got to the D.III I needed to get the shape of the various styles of fairings worked out and I started looking. Like everyone else, I had always seen these done as painted aluminum but it's just not so. Just because you see it in art, decal or model instructions, and other peoples models doesn't necessarily make it true. But don't take my word for it, look for yourself. Try and find one that is definitely painted aluminum.
PS, check out that wheel disc in the Voss photo above, you can see the fabric flap for the tire filler and the chipping.
