Ah, this was probably mine then - I shifted it at Hemswell last weekend in my bi-annual attic clearout.
My own instinct was that it was, once, a taller vase that had been broken and then ground down because the rim cuts right through the textured pattern. I also felt that the silver base was a later addition, possibly also to mask further damage.
The design is very familiar, but I never bothered to spend time looking into it because of my concerns mentioned above.
