My sources show pretty much standard Heer feldgrau M-42 uniforms, Stik... There's a couple that look like the trousers are a darker feldgrau than the jackets, may even be a brownish grey (Italian, perhaps?) and the M-43 cap looks like it's SS Mausgrau, but I think it's just lighting.... I don't have a scanner or I'd post 'em and let you decide, since colors on computers are relative... The Waffen-SS bergers look like all standard Mausgrau, with the elasticized puttees on the mountain boots..
At this point, I'd have to say, "your guess is as good as mine."... I guess I didn't develope an interest in mountain troops since they aren't too popular (read: numerous) in the reenactment world...
