I have some cp delf floating heads and one resinsoul boy body 62 cm in NS that I bought second hand (don’t know the age). So, the picture is a Luwen Vampire in ws. Another cpdelf head in ns nearby as reference. In my opinion, resinsoul neck is a tiny bit too long. But if you like a long neck, the proposition is not bad.

And if it's the right body for the right head, the neck could always be sanded down a bit. Mobility & fit seemed good?
