Not suggesting it is but I've seen North American amberina vases that looked similar. Some pieces with the bulbous base, some with the turned crimped rim with the 'nipped up piece'

. Unfortunately I don't recall seeing anything recently that had both features simultaneously. The yellow to red transition all seemed to be more gradual in the pieces I recall seing than what yours shows.
Being on your side of the pond though I suspect yours is probably closer to home.
