With antiques, there are several factors: age, condition, historical significance, and uniqueness.
In other words, (I give hypothetical figures since I'm not a dealer) a telegraph machine in poor condition that was one of 100,000 made might only be worth a few bucks. But the telegraph machine that announced the end of the First World War, and has been preserved in a museum, could be worth hundreds of thousands.
You'd have to consult an antiques dealer to get a definite answer.

HOW THEY MADE A MORSE CODE MACHINE Samuel F.B. Morse and Alfred Vail developed an electric telegraph which sent pulses of electrical current to control an electromagnet that was located at the receiving end of the telegraph wire.

Joseph Henry. He did not patent it though, and Samuel Morse stole his idea and patented it.

A telegraph works by sending a series of electric pulses through a long wire, to another telegraph device which then interprets the pulses into a series of clicking sounds. Depending on how long the lengths of the clicks are, there is an "alphabet" called Morse Code that the person on the other side of the telegraph can use to understand. The telegraph system was the first step to the development of the telephone. <><><> The old fashioned telegraph system used lines similar to telephone lines but did not use speech. It was used to send messages from one place to another by using electrical on/off signals, similar to the dots and dashes used in the Morse Code. A person who wanted to send a telegraph message would have to write it clearly - using block letters and numbers - onto a piece of paper called a "Telegraph Transmission Form" and had to take it by hand to a "Telegraph Office". A person called a "Telegraph Operator" then had to read the form and tap-in each of the letters and numbers into a machine called a "Telegraph Machine". The signals made letters and numbers appear on a similar machine at a "Telegraph Office" in the town where the person lived who was to receive the message. The machine at the "receiving station" actually printed out the letters and numbers onto a strip of paper just as they were sent out from the keyboard of the "transmitting station". The strips of paper were then pasted onto another sheet of paper, called a "Telegraph Reception Form" and that was hand-delivered to the person it was addressed-to. <><><> If you mean a telex machine, it has a keyboard like a typewriter and also has a printer . If you know someone you want to send a message to has a similar telex machine, you can set up a telex call to their number, just like a telephone call but with no speech. Then you can type in your message and the the telex machine at the other end of the line will print it out.
you can check the serial number on the singer website but according to the one you gave it was made in 1910
