Interesting Telegraph Equipment – Solved!

We’ve had an interesting enquiry regarding this lovely old piece of telegraphy equipment and as our research continues we’ve uncovered some interesting answers!

We often receive e-mails from people wanting to know more about their hidden treasures or mystery antiques. Most items and any related information finds a place on the Grace’s Guide history pages and we’re often able to look up more details for our reader straight away. Sometimes however, we need to do a bit of extra research and with items like this, we’ll ask museums, collections, enthusiasts and experts to help us find the answers.

In this case we got in touch with Porthcurno Museum in Cornwall, The Central Archive of The British Museum and The Siemens organisation itself. All proposed excellent information, but the most certain came from Professor Emeritus Tom Perera of the Montclair State University. Take a look at his online telegraph museum.

He expertly identified the object as a Siemens Code Transmitter designed to send a specific message in Morse code when activated. The message in this case being “S” and “I”. Adding to this he tells us it was most likely an alarm device that sent those characters to alert the main station that an event had occurred at the site, identified by ‘I’ ‘S’ and dated it between 1890 and 1930.
