How little mole made mouse well again

Most Little Gems visitors will fondly remember the cartoon from the 1970s when it was shown by the BBC. I have very little information on exact dates, however, I do know that "The Mole" was shown on BBC1 at 16:25 on the Friday 09th May 1975 (my RadioTimes collection helps yet again). Most of the episodes ranged from 6-10 minutes (others, though were much longer) and were typically shown before Jackanory on a week day. I have included some images below which may jog a few memories. Over thirty books have been produced about the Mole. "The Mole" was as popular in Czechoslovakia as Bagpuss was in the United Kingdom.
