Victorian cased glass vase with applied flower

This Victorian glass vase is made from three layers of cased glass, clear over a shaded peachblow type pink, with a white interior. The vase has a very distinctive top rim, which is peaked like a jack - in - the -pulpit, crimped, & folded over all around. There is a pale amber applied crest, pale amber leaf trail, & a pink & white flower. Sadly, the flower & leaf trail have suffered some damage, but the rest of the vase is perfect. It measures 17.5 cm tall at the highest point, 8 cm across the folded top rim, & 5.3 cm across the base, which has a rough, snapped pontil mark. I have seen a pair of these vases on eBay listed as Stevens & Williams (like pretty much anything with an applied flower usually is). Regardless of that, I do think it could be English in origin.
