As for Rillington strain Beddies nowadays, most working stuff have Rillington running throught them, but when you check it out, the amounts of Rillington can be negligable.
I went to see quite a few litters of Bedlingtons in the past few years, and very few of them were what they said on the tin.
I went to see one litter of advertised "Rillington Bedlingtons" and as soon as I saw the parents (weak looking, cotton wool coats etc) I smelled the bullshit.
