That's an interesting link - I overlooked it before, yes I see what you mean and am more confident this is a Beranek flower.
On another note I recently bought some Skrdlovice off eBay and I see same patterns in the linked Beranek catalogue. I will have to wait till they arrive to ask if they are Skrdlovice or later Beranek. I know Beranek continued many of the same shapes through.
