Wow! I didn't see this.The way I heard it was that Ashbrook had them developed to a strong quality, but that Overton took them over. The gentleman telling me the tale implied that perhaps they had not faired as well under Overton's care. I cannot say, though, because I've not seen them myself.
I have known both of these gentleman for over 30 years and if there was any improvement to the Sussex, it was done by Gary Overton. There are some people that will say all kinds of things, but that does not make those statements true. It is only true if it is posted on BYC and it only remains true until someone rebuts it.
there is a lot of mis-information online.
