| CK.{Mr Clark} from RHC.{R. H. Coverley - Production Engineer} X 2894 RHC{R. H. Coverley - Production Engineer}2/LG5. 2. 20. RE TUNGSTEN CONTACTS X. 2894. With reference to the above, will you kindly note that we have fitted the 2 Tungsten rivets supplied, to a blade and screw for a chassis contact breaker and handed this to Furner. I noticed that these are only tungsten tips deposited on a rivet. With reference to the short piece of tungsten rod which you supplied and which was obtained from the Fan Steel Co. U.S.A. we are unable to machine this; it could be done by grinding but that would entail a fair amount of scrap and I do not consider it would be worth it. I attach the tungsten in question hereto.
