Single Position Letter Sorting Machine (1959)

This machine (known as a SPLSM) was originally used in 1956 in Norwich and later in Ipswich. It is an example of the first successful British sorting machines that remained in use for 30 years. Letters would appear on a vertical conveyer belt in front of an operator. The operator would then enter a code based on information within the address so that the machine could sort the letter into one of 144 boxes for delivery.
