No,, pretty sure these are transferware !! First of all,, does it make logical sense that any factory/pottery would spend triple the cost to make something but not put the factory/pottery name on it !! I mean thats why they are producing these,, to sell !! But how would anyone know where to buy them without a name ?? Doesn`t make any business sense does it ?? The number on the back is the mold number and sometimes they made items in more than one run and mold numbers did vary even with identical pieces depending on the run sequence !! They had more than one or two molds for the same piece !! As to the pattern,, just the placement is different but of the ones I could see well enough to match were almost identical !! They could vary slightly after firing but very little !!
