Found nothing in any of my books, with that Pattern, very unusual for sure. Without maker marks one would have days of looking through patterns. Might be possible they are special made. Maybe for someone in Saudi Arabia, sure does resemble their coat of arms like sapphire found. But a special order made with just German Silver would be kind of expensive, one with money would most likely go for Silver, at least plate. Anyway I will keep my eyes open just in case I see that pattern.
