Met Jeff F a few times, years ago at Harcolmbs International Terrier Matches, nice bloke too. Never seen his dogs go but i've heard good and bad reviews about em over the years.
Never met Levi, even though he was a lot closer than Jeff, in Cheshire. I've seen a couple of his dogs out and they knew their job. Never heard a bad word said about any of his dogs when he was alive.
