Then you will have seen my late father in it - he played a farmer in one episode and the "knacker man" in another when the cow runs away from him as he is driving it to market and returns to its stall.

I don't think I have managed to see the episode you refer to. however.

There is to be a mini series shown over Christmas on the BBC about the young James Heriot at Glasgow Veterinary School with a Scots accent that he never had in the original series!
