Matt, Like the Concentrica post, it's hard to say as there are a number of red centred hybrids out there like this that have been done over the years. The closet I can think of to this one would be 'Crimson Nest', the pup looks near identical to some of these pups I have at the mo, but sorry can't be 100% sure.
Cheers

Thanks for the reply Graeme. It certainly helps give me some direction with possibly even id'ing the parents. Cheers Matt
