i was in a tv advert in the late 1970s does anyone know if i can get a copy?

The advert was filmed at mclarens pushchair factory in long buckby uk. The assembly line i was working on was filmed and the advert went out on early evening tv my family saw it but ironically i was on way home from said factory and never got to see it. This was in the days before home video so i have no idea if the film is still in existence. Is there anyone else reading this who worked at mclarens at the time? do you remember the ad being made and were you in it ? have you ever seen it?
if anyone out there has any information i would love to hear form you

Try You Tube, you’d be amazed at the videos they have. Also try to Google it and see if you can find it in some archive.
