Oh it is indeed! It is absolutely gorgeous.
And it's not easy to find pieces from that era. They are around and in museum collections but I don't often see bowls like this and certainly not this big.
Have you had a search online of the museum collections? Oh I have just thought of something.
You could email Harrach directly.
Again my memory isn't great but I seem to remember there being a fire and the pattern books being lost, however,they just might be able to help you a bit more especially as it is such an unusual piece.
Also, in the Corning musuem, and somewhere on this site (I'll see if I can find it in a minute) there is a link to an early Meyr's Neffe catalogue I think.
I will try and find the link for you and post it later or tomorrow morning.
The Harrach book is fantastic - and huge. I've read it in sections over time, rather than reading the whole thing at once which I keep meaning to do!
