In 2021 Telecommunications Heritage Group member, Jay Day, kindly donated a hoard of photographs he acquired from someone who must have bought them at the massive auction held by BT when they disposed of their museum collection and set up Connected Earth in association with other museums. (Picture top right)There were over 1500 prints which have been scanned and made available for private study and educational use. Virtually all are of Post Office or British Telecom origin. Please respect the copyright and credit the source as requested if you use a picture. Commercial use will require a licence and probably a fee

The main photo images were scanned in greyscale (or colour where needed) at 400 dpi. I tried some samples at both 400 and 600 and could not tell the difference, so chose the more economical size. The reverse was scanned at 200 dpi to show any annotation on the back and the negative number. The initial scans were saved in JPG format with only light compression - 15 in my photo editor, where 1 is no compression and 99 is the most. The two images, front and back, have been combined into a single PDF file for display, but the original JPGs have been stored separately.

I've split the pictures into subject groups listed below. Click picture in the left-hand column for a larger view. The archive pictures are hosted on Google Drive under the links shown below the photo. The display defaults to thumbnail view but can be switched to a list view to show the negative number as the full title with the description gleaned from the BT Archive index.

Items that I deemed of more limited interest I combined in a common PDF file with the pages numbered by the negative number. These are:

There's about a couple of hundred that are unnumbered. Some have the Post Office or BT stamp but either no number or only the date. Others are devoid of an official number - some have a photographer's studio reference.

I've found that Google Drive is a bit quirky and fussy about which browser you use. It works OK in major browsers like Firefox, Opera, Chrome and MS Edge. The PDF reader is slow to load unless you are logged into Google. This web page works OK on a mobile screen but is best in landscape mode.

Cabling in wartime

Cabling in wartime

Work for the Post Office was a 'reserved occupation during WW2. Work continued to keep communications running for both civilian and military needs. In the photos, which would not have been published until after the war, we see a new cable being installed in the Severn tunnel (see below) and at Barmouth. There were also emergency repairs to cable routes damaged by bombing.

There are more pictures from WW2 in the section labelled 'Wartime' below.

Cable ship Alert

Cable ships and submarine cable

Cable ships have played a part in establishing international communications since the middle of the 19th century. Telegraphy helped to bind the British Empire together from the 1860 onwards. The first telephone cable to France was laid by HMTS Monarch (No. 1) in 1891. THe name Monarch has been applied to a succession of cable ships.

Ductwork in Victoria Street 1908

Cables and ductwork

In the early years of telegraphy and telephony, subscribers were connected by overhead wires suspended on poles and running above the rooftops. The untidy mess led to a move to run the cables underground. Using ducts allowed more cables to be added later as demand increased. The oldest pictures are from early in the 20th century.

Clocks and watches

Timekeeping played an important role in all aspects of Post Office engineering. Telephone calls were charged by the minute and rates changed during the day. The postal service also needed clocks in Post Offices. The range of clocks and watches is staggering.
