Thanks guys, it doesn't sound promising.
I did some digging around last night and it seems Emperor Toad and Murawski are one and the same. According to his Facebook page, Murawski Miniatures are being cast by Skytrex now, but on a contract basis I think. His range of French Revolutionary Wars figures has been sold off to Skytrex very recently, so maybe Murawski Miniatures will go the same way.
Its a shame, they are very nice figures, and just what I need to complete a small project.
