Craig,
I'd always wanted to hunt with Ken as well but he'd not gunned for years and years even when I knew him in the mid-80's. He'd been a guide at one time and actually gave advertised calling lessons at the club he worked for.
I've got one of his very early goose calls without the name branded on it and the extra large bell mouthpiece. It's the earliest semi-commercial type. The only thing earlier is a straight barrel goose call made from cedar he did when he first got started and just gave to friends. I only know of one of those, have been hunting one for ages to add to the collection.
