Tile ID - Help! Schaeffenacker?

New here, so hoping I uploaded my images properly - It has been suggested that these tiles in my fireplace surround may be Schaeffenacker? I have done a bit of research, but they don't look like a lot of what I have seen on ebay etc that is identified as such. There is a lot of texture & brilliant color glaze used-whether or not it is visible in the images. They measure 6x6" and based on my limited experience with ceramics-they look German in origin? I have found another tile in the greenhouse, marked made in Germany, which has an impressed mark with a circle interrupted by 2 squiggly lines & a bauhaus font style m (or could be w-not sure which end is up). It also measures 6x6" but doesn't look like it would have been from the same manufacturer as it doesn't have the same texture, but uses similar cobalt/teal glaze.

Finally sorted out how to post pic. Sorry about that. I cleaned the old felt off the back of the other tile I have found and the mark on the back is actually V with an eagle over the V at the top of the circle with the squiggly lines running horizontally through the circle & a B below the squiggles. Villeroy & Boch? I don't find anything remotely resembles this on a google image search.

a stunning buy Meg and I think you're right about the maker

If anyone had read the original post properly, they would see that the mark Meg refers to is on a different tile completely and not the ones pictured on her fireplace surround.
