The images below were captured in a collectables emporium in Australia using a phone (hence the image quality, sorry). The item is about 22cm high and heavy walled. The "worm" impressed into the pontil mark has a passing similarity to the Strathearn leaping salmon, but possibly close enough to be more than coincidence. The shape of the vase could pass for Strathearn, but it is not as well made as Strathearn items I have seen, with a small bump and some stray colour pickup. What's more the colours don't look right (to my limited knowledge, at least).
Who makes such things? It might even be an Australian studio piece, in which case the question becomes: What's their connection to Strathearn?
