I picked this up the other day at an antique shop here in Southwestern Ontario. I have no idea of its origin or its value. It washed up very nice. It has a small,(1/2 inch?) pinhole. On top of the "saddle grooves" it has 2501 (5 or a 6, I can't tell) K 01 and the on the other side it has IFO 58. Any foreign porcelain collectors have any ideas? ANY info on it would be greatly appreciated.

Thanks, Kyle Waters
