These have been out for awhile and have received two volumes selling for £3.95 each from a mail order DVD firm.
Fascinating to see, having remembered the 1977 Euston Films version, seemed strange seeing a mix of VT and film for these original episodes made in 1972-3.
The BAD NEWS however, is the distributors, Clear Vision Ltd, have removed all original Thames idents and break bumpers. The original end Thames end cap is also missing, typical of a VHS release fifteen years ago. In its place is a mid 1990s version (although correctly dated). UK Gold would've been proud.....
Picture quality is excellent, which is a plus point.
Verdict- worth £3.95 but not more in view of the horrors of editing, clearly a no no in a modern release. Clear Vision- please take note!
