Victorian cased glass fish vase/centrepiece on mirror plateau - Walsh Walsh?

I bought this unusual piece around 14 years ago...at the time, it was mounted on a wooden base, & was sold as a Murano fish figurine. However, there were various aspects that never added up to it being Murano, especially the metal fitting on the base, the rustic thorns on the fish, & the amount of ingrained black dirt in the applied decoration, which strongly suggested a Victorian era piece. Murano fish figurines are smooth & simpler in form, & do not have the rustic thorns. I also knew immediately that the wooden base was incorrect, & eventually deduced that it would have sat on a mirror plateau, after I acquired another Victorian piece on a mirror base, which had an identical metal fitting. After much searching, I finally found an appropriate mirror plateau last year, which I feel is of the correct size for the vase...the screw in fitting was a perfect match for it. The reason for my tentative attribution to John Walsh Walsh is due to the similarity between this fish & the vases they made with applied fish, as well as the rustic thorn pull out decoration, & the distinctive bright pink, which is seen on their Palm Tree vases. The vase alone measures 24 cm tall (27 cm including the mirror plateau). It measures 12 cm wide across the mouth of the fish. Made from three layers of cased glass - clear over bright pink, with a white interior, it is decorated with rustic thorns & has applied details in clear glass. A small clear rigaree encircles the base near the metal fitting.
