The plugs we wish to be tried out on 5.B.IV are type 850 and 851. We are handing to you three 851 plugs and are arranging for a supply of type 850 plugs to be sent direct to Chateauroux. The 850 type plugs are those we are most interested in these being less experimental than the 851's which have thin platinum electrodes. Hs{Lord Ernest Hives - Chair}/Wst. | ||
