NF = Retro B-Uhren?

I have been interested in the WWII vintage B-Uhen, which the NFII is a great copy of. But the band and case color arent quite there. I opted for the NF Vintage which is on the way.
I'd love to see a traditional brown band with the rivets, or even a titanium case to look like the old "blackened stainless". Maybe a PVD coating would work? I think this would take off seeing that NFII is doing well and Laco is unavailable in the US and. Any thoughts?
