				 RESISTANCES, Variable, Wirewound, 10K Ohms  ZA/CAN 4441 
 
			
			In terms of the 52-Set receiver circuits, this component is the R.F. GAIN CONTROL, Circuit Reference ‘R33A’. 
 The original manufacturer was C. G. Meredith & Co. Ltd. but I have yet to find anything about them on the web. Probably a long gone company by now.
