At Manch, several Lamson tubes came out of the ceiling to the FPRS assistants.
It was occasionally referred to as The Steamship Enterprise. One of the VCR ATSA would often ask for a bag of crisps from the 4th floor goody-box. The crisps would be reduced to granules and sent up the pipe.
Many supermarkets have modern 'Lamson' systems to take cash etc, from the checkout positions to the cash office.
Assistant at EGNX did the 'pen down the tube' thing in the late 60s and they nearly had to take the control tower building apart to find it.
