My farther William (Bill) Watters (TM2 Lighting) worked for the BBC for 28 years until 1975. 

I would like to ask if any members know about a program, pilot or ?? called the Scribble Experiment

I have a note of thanks to my father for his work on "this experiment" from a Vision Organiser "E. G. Dann". This was written 17th March 1970. It mentions Pat Dowling who I believe was the producer of Vision On and other similar programs around this time.

The subject field of the letter refers to: "Scribble Experiment : 14.3.70 TC3"

From other letters I think 14.3.70 is the date it was recorded. "TC" is presumably Televison Centre as that's where he worked. Also Lime Grove.

The letter also says "if this production comes into the schedule"... so perhaps it was just a pilot that didn't make it or it got renamed?

Any info welcome!
