WMF acid etched biscuit barrel and claret jug. Hosch 1906-1912?

I've had this biscuit barrel for awhile and just recently found this matching Claret Jug at auction. The metal work is marked WMF. My first thought was the glass is Legras and Cie but it was suggested on a French Art Glass group that is might be bohemian, possibly Harrach. My searching has found a very similar design by Moser, but nothing definitive. Any ideas?

Addendum: I've added a photo of the line drawing from the Hosch catalog (1906-1912) that looks very similar my pieces. I think I'm getting closer.
