I agree Cyn, he does look nice and big, but the angle of the picture made me question the deepness/broadness of his chest. That's the problem sometimes with buying a bird based on pictures. Unless you get multiple pics with different angles, you don't really get the right impression of the whole bird.
If he is a big broad bird, then he is a really good starting point for breeding I think. Really good coloration, wing carriage. Comb needs work. If he isn't, a cross with some larger hens will help that in a few generations while keeping the good points that he provides.
