three piece set of bavarian dishes

these are all with a lattice type work There's a plate, bowl and basket They could be hand painted  and they all say bavaria. The plate has 4698 over 7 imprinted and an FX I think, also written 1169 over 659.  The basket has 659 written and BI, 4919 over 0 imprinted.  The bowl has 1169 over 659 written and 1179 over 2  and X  or XO imprinted. The plate has a piece broken off the edge 1x2". It was glued back in.  The other 2 are perfect. This has not been used much. They do match each other and all have a black edge.  I would like to find out about this. I haven't been successful in finding the marks anywhere.
