		In November 1940, Plessey of Ilford put its factory 
		underground. 
		 
		I have been able to scan a number of 
		official photographs which were to be lost with the closing of a 
		facility 
		It is difficult to know whether there is 
		any copyright on these photos. If anyone believes they own the copyright 
		please contact me 
		 
		Similarly if anyone worked at the facility 
		and has memories to share I would be very pleased  to hear from 
		them.
