Gentlemen
A very long time ago, in the late forties, perhaps when 'our' Norman was a lad, grocery shops such as the Co-op used to have a central cashier's office, rather than individual tills located on the counter.
The customer would buy her half pound of lard and the shop assistant would load the money and a receipt into a small brass pot. The pot was then attached to a system of exposed overhead wires, an overhead handle was pulled downwards and the pot whizzed along the length of the shop to the cashier's office. A short time later the pot whizzed back, now containing any change and the 'paid' receipt.
Who made this system....what was it called...?
(nb Do not confuse with the later system where the process was the same except the transfer was by means of a cylindrical container traveling within enclosed tubing and propelled by compressed air..'Lampson Tube'? This system, until recently, at least, was still in use in some of HM's warships)
