This M&K marked Pitcher seems to have an ivory handle? The marks are to the left and right of the top of the handle.
M&K is pretty clear, and I've seen references to late 18th to early 19th century Vienna? The other mark is very worn but looks similar to a a rouind mark with a cross in it, this was on the Vienna piece with M&K I found online here:
