Staffordshire spill vases

Hi there

I bought these from an estate sale. I believe they are Staffordshire spill vases from circa 1860. There's no stamp, the only difference I see is that there is no "shrubbery" like there is in the example in the link below. Is this a piece that's often replicated? I want to sell them, just want to be confident that they're original.

Thanks in advance.

They look right to me. The maroon colour in the holder part is different from the brighter orange colour one often sees, but if a repro, then an antique repro!
