What for?
And if I recall properly, was it only one fella that accepted the challenge with his collie/grey, and beat him?
Sounds like the guy had egotistical problems to me, throwing out silly challenges like that.
Not everyone is/was into numbers, and not everyone is/was gullible enough to believe all the bullshit, me certainly being one of them.
There were plenty of lurcher to lurcher bred dogs around then, that no- one really knew the real, never mind exact, breeding of. To me minshaws were just another case of exactly that
