Wilcom has a few that are close, but definitely with differences.
While the application of it is in puff, that doesn't mean that it is a puff exclusive font. Most script fonts are easy enough to move to puff compared to your block fonts, so I wouldn't go directly off the application. The biggest concern would be the stitch width that may have changed from a regular font (regardless of font type), so may want to look at thinner ones as well.
That's if you need access to more copy from that font. If it's just what's pictured, that's easy enough to replicate (depending on digitizing software, even if wanting vector and not embroidery objects, easier to do with digitizing software compared to vector software, replicating tools are far more efficient, at least in my experience).
