| To EFC. from R.{Sir Henry Royce} Copy to CJ. [Handwritten annotations at top: 2CA, D, 3] [Stamp: ORIGINAL] 26th March, 1918. R14/G26318. [Stamp: RECEIVED 28 MAR 1918] [Handwritten annotation on right: 338] X.562 X.1607 RE TREMBLER COILS. The one I have on 7 CA. is working nicely. There is no urgency in the matter, and I should prefer to wait until you had a good one to send. To enable me to get some further experience in this matter, I should be glad if you would send one for four volts, and one for six volts, both of the improved type of trembler to the latest suggestions.
