| x2894 C. EFC. BY/RD2/ML.9.7.25. X.2894 - TUNGSTEN CONTACT POINTS. Y46462 Would you please obtain 12 sets of Contact Points to D.51047/8, prints herewith, from Johnson Matthey's for the Experimental Dept. to test. The tungsten should be the purest obtainable and I suggest that at the same time as the enquiry is sent, we ask them how they would propose fastening the point to our contact finger D.50075, if then they have a good suggestion we could allow them to fix some for us.
