Letter from R. S. Wright, Newton & Wright Ltd., 72 Wigmore Street, London, to James Mackenzie Davidson Is glad Mackenzie Davidson is still liking the [snook] machine so much. Agrees that once you have tried it you are unlikely to go back to a coil. Expresses a desire that there was some way of convincing the 'somewhat old-fashioned' War Office of its superiority. 6 July 1917
