Thanks mummza.  Unfortunately, I'm housebound and couldn't even get to Cardiff.

Also, I've always wanted to try salt marsh fed lamb.  No sign of it in these parts.  It is considered by many to the finest lamb ever.

Incidentally @nGoose1, I've never heard of Welsh Blacks, only Welsh Black Beef.  I lived close to Dartmoor for 42 years and Devon Spring Lamb is wonderful.  Again, I've never heard of Dartmoor lamb.  Usually comes under the heading of Devon Spring Lamb,

The person who does my shopping, mummza, is Mr Tesco, lol.

T.D.
Any ones guess what Mr. Tesco will give you, probably New Zealand. Nice place, nice people. But the lamb is god knows what from god knows where. Unless of course you are in New Zealand and you know the product and its origin.Hugh Fearnley's words, I agree with them. I must say, Tesco has a bad rep at late with products and origin.
As for those kippers.
For the sheep breed:

My friends ones, are now old enough to be called Mutton, they were hogget. I dare say some lamb is in the pipeline in a few months time. It is farmed on Dartmoor, hence the farmer saying it is Dartmoor. They could say it was European, that would be different.
I have also traced the other Mutton farm, also very good.
It’s called  ‘Higherfingle Farm ' Devon ,it does mail order and can be found at Totness and Royal Williams Yard farmers markets.
The well hung meat company also has meat on Dartmoor, via the National Trust, so probably something special there also. They also do mail order.
Good luck getting your meat, last time I could not get good meat, because of factory farming and price. I went vegetarian
