These are my Wyndham-Gibraltar vases:
pink is acid dip-etched - smooth edges - looks less high due to being really wonky
green is not uranium - slightly rough edges especially at the base
blue is not designed for an insert - ground base
both frogs are shiny clear
the panels of alternating sizes are absolutely same on all three vases as also the stepped feet are
image 4 is a smaller ceramic version, very faintly marked, but could read a number and MADE IN ENGLAND - and I like it too
