| To BY. {R.W. Bailey - Chief Engineer} from EH. c. to DM {D. Munro} , EH2/LG9.9.19. 9th. Sept. 1919. RE BOYCE MOTO-METER. X.3639 We do not consider the Boyce Moto-Meter is in any way as nice a fitting as the capilliary tube Thermo-meter which we have standardised. It is an unsightly thing for the radiator cap and heavy. We have tested this meter and find that the temperature of the different marks are as follows:- Boiling 80ºC 74ºC 63ºC 51ºC We are keeping the Boyce Moto-Meter as we think it is hardly worth while sending this on to Mr. Royce. EH. R.R. 235A (500 F) (S.D. 408. 26-4-17.) Bm. 2156/13. | ||
