This is what I know about these players.

I was told they were purchased direct from the BBC in the early 1970s and used throughout the 70s and 80s.

The heads were also replaced at some point I am told.

The players haven't been used since then but have been stored away.

All the leads come with them and are numbered.

I have connected it all and there is one umatic video which seems to play on both players.

The mixer also registers the timing.

I don't know how to connect to a TV so can't be sure all functions work but was told they all did when stored.

They are very heavy - 25kg each so I will have to courier them separately.

You can collect if you wanted - I am at ig5 0jn just off the North Circular.

Cosmetically they are pretty good - few marks on the casing - see photos.

Overall a very rare find originally used for editing BBC programmes I guess.
