There is a long list of very helpful comments already available against the English DVD version of this series and I won't repeat them except to say that this American-issued set also provides excellent nostalgic entertainment.
The principal difference appears to be that the English set contains five discs whereas this one has only three (not the 4 listed) - but still includes the full set of 39 episodes. The listing also describes it as being in colour, but of course it's in black and white. The listing may since have been corrected.
The episodes appear to have been collected from various sources and vary considerably in print quality. Some still include some (American) sponsors' messages, and are well-worn with noticable scratches and spots, while a few others have been reprocessed to a like-new standard.
One episode (so far) even has the alternative title: "The Adventures in Sherwood Forest" (rather than The Adventures of Robin Hood)!
And you can't rely on the closing credits for information - they appear to have been tacked on at random (perhaps to get round some of the sponsors' messages), so that the cast list often shows characters and actors who don't appear in that particular episode. I've only watched the first disc so far, but am still looking forward to seeing young versions of Patrick Troughton, Thora Hird and Paul Eddington as well as many other familiar personalities who have risen to prominence over the years.
I well remember this series from my 'formative' years - but I hadn't realised how utterly gorgeous Bernadette O'Farrell was!
Most enjoyable - and a great purchase!
