Intermission pics on old TV?

The Names..I don't know.A surname "Scottish" and two first names....

Is the second part names of broadcasters / presenters from the same era?

I know the "Potters wheel" was used for intermissions on the BBC.

Yes katty and Cold Sweat. You're a bright lot! 
The 4 pictures were all taken from "Interludes" which were a nightly feature of early television.  Ploughing, London to Brighton in 4 minutes, Windmill and Potters Wheel.

The names:-
Macdonald in this case is a first name.
They were continuity announcers in early television.
Macdonald Hobley, Sylvias Peters and Mary Malcolm.

LOL... finally something I knew the answer to ( I even knew the presenters names link) and everyone beat me too it Brought back a few  happy memories though......

Aww Baz, never mind      I have marked it down as a victory for you. 

 Thanks Brisket I have to admit that the names provoked almost instant images of my childhood....... Especially Sylvia Peters....

Being auld is sometimes usefull.

This is the original BBC interlude for London to Brighton in 4 minutes - one of the best of all of the BBC interludes:



and another one which is unusual (poor sound quality though):

I knew the answers. 

Katty and Coldy just beat me to it. 

I was gonna say they are all black n white
To be fair I didn't watch British telly till I was 11yrs old!

I thoroughly enjoyed watching that London to Brighton in 4 minutes video!

It is indeed ........especially in one of Briskets threads 
Keep em coming Brisket - you're a star 

 Aww Shucks Soozy

Blimey! I'm preparing m'self for the Eileen Fowler material.
