FWIW, the silicone grease that I have used more recently has been Dow Corning MS4. That is specifically described by them as being a lubricant suitable for wiping contacts, as well as multiple other uses.
The grease we used in 1961 was probably a 'Radiospares' (now RS Components) in-house brand, but would have been made by one of the major chemical manufacturers. The technician in charge of the TV shop was ex-military - it's way too late to ask him but I would almost be prepared to bet that he had first seen the technique in the forces. 73 Roger VE3ZI _________________ Topband Reflector Archives - http://www.contesting.com/_topband
