whats happened with them john ??, i used to collect my ferrets from neath railway station off them, always well handled, good condidtion and worked well to be fair if thats what you specified. I spoke to a lady from there once, asked her how they didi it, aparently there was an old pig farm with lots of pens, and they kept the ferrets in the pens with artificial burrows etc made in them, so they were always running through them from an early age.
But yes, abot bros, thuxton, norfolk brings back memories, my grandfather put me onto them as he used to get feerts from them as well MANy years
