Pottery Flask, Carstens Tonnieshof? - Greece / Greek

Stoneware Pottery flask, Carstens Tonnieshof Germany maybe? Marks on the base with letters & numbers but hard to read.

I can see a possible O and R at three and five O'clock and is that an X at eleven O'clock. Can you make out any other letters?

Not really, I'm going to try and bring up the marks more clearly with pencil shading or something. I can just make out the O R and possibly S9/19 in the centre running left to right from sides of the vase. Such a small area the marks are kind of squashed together, will get back if I can make the marks any clearer. Thanks Pugmill for the input.

Possibly one of these
