The number you see on the bottom is the factory mold number !! Is that a paint run on the second pic ??

No it is not paint. It seems half of bottom is glazed and half is not

I am not talking about the bottom !! I am talking about the pic of the second vase upright !! Looks like a run in the paint on the white part that is on the neck of the vase !! Where the blue runs into the white !! The bottom is made as most all are !! The center is glazed but the foot is not !! Thats what it should look like !!

It looks like the original paint. The same colour is on the other side too but less visible.

Without a factory name on the bottom no way to know what company made these vases !! They are typical of early 20th century styles ,,maybe 1920`s through the 1930`s !! There were just too many factories working to even guess !! And the mold numbers on the bottom do not help !! Sorry !!
