Unknown mark from Germany (?) ca. 1750 (?)

[Stantheman]

Hello! I came across this pair of candlesticks. I tried to identify silver marks but I didn't get it yet. They are not clear which doesn't help. There are just two marks on each of the candlesticks.
One mark (on the right hand side) looks a bit like a bird ? standing on tall feet (heron or stork bird ?) but it's just a guess. The other mark... I have no clue what it resembles. Are these letters or something else? Actually I don't even know which one is the city mark and which one is maker's mark.
The candlesticks look like coming from mid XVIII cent. central Europe - Germany or its neighbours (Austria, Switzerland?).
Maybe anyone of you saw that marks ad will be able to help me. Thanks!

the left mark looks like a head of an aries or an goat.

could it be Schaffhausen?

Thank you, Teodorich. I've never seen Schaffhausen silver mark. So I have no clue. But anyway thank you for your suggestion. Kind regards!
