legbar cross

Does anyone know whether this is a mix or a pure breed of legbar/leghorn/cream crested legbar? On the Internet I can't find exactly similar roosters from these breeds, is it a mix?

I love legbars and have crossed them over a few other heritage breeds and want to share the results (and would LOVE if others shared their results too). When i started crossing my legbar it was really hard to find images or what the babies might look like so i imagine there will be others out...
