Master clock. Can anyone identify where it came from please?
For a couple of years this rather nice ITR master clock has been dangling from my dining room wall when I bought it ( £70 bargain ) it came with a small envelope attached to the inside of the case which is apparently a letter from the GPO to the guy that bought it off them in 1971 along with the receipt for the £1.50 he paid.
I have attached a couple of photos of the letter which states it was sold as scrap from " the old radio station Brentwood after the ETE had vacated the building " it's that that id like to shed some light on. Unusually for an ex GPO clock it's an ITR not a Gent etc it's the weight driven self winding variety and had an electromagnetic pick up attached to the pendulum when bought which I assume provided impulses for seconds. Any thoughts gratefully received. |

That's nice - it's older than my ITR clock which (judging by where I found it) dates from mid 60s. The ITR slaves I have are all one minute pulse types. I wonder which Brentwood we are talking about - I went to school in the one in Essex, but I can't picture where your letter might refer to.
cheers Mark

Synchronome? The GPO certainly had dealings with them, they made the talking clock system at one time.

£1.50 for a master and some slaves... BARGAIN, even back then!
Does anyone know what ETE stands for? |

I don't know if they were going in 1971 though. [Later] No, formed in 1984: https://www.ete.co.uk/about-us/ |

In times past, it was quite common for PO to sell off bits of kit to interested staff. Receipts were issued to keep it all above board. (I got quite a few bits of testgear this way). In more recent times the liability lawyers put an end to that....
