i have a fireworks cut that looks exactly the same. Unfortunately it was in my computer that has crashed.
I found it originally as a GSD file on this website:

I was able to convert it over to an SVG file with inkscape and then made the cut. Sadly, I did not save my files and lost a great deal of them with the computer crash.
