Your note EFC1/T14.7.24. &Specification EFC2/T11.7.24. X.4617. 40/50 HP. Battery - Our specification 301. Your note EFC1/T12.3.24 & Specification EFC1/T8.3.24. Herewith I send you copy of letter from Messrs. Peto & Radford with regard to the two specifications above quoted. I have communicated the gist of Peto & Radford's remarks to the Chloride Elec. Storage Co.Ltd. and await their reply. In the meantime, I think you will decide to look into the question of the height of cell for the 40/50 HP. battery. Clause 8a, your specification 301 (EFC1/T8.3.24). In said specification you give the approximate height of the cell as 8.3/32" and the absolute limit as 8.1/8"; whereas according to Peto & Radford's letter they are making the cells 8.9/16" high.
