We are arranging to set the four regulators in our possession to the above limits and will return them to you if possible on Thursday. We shall be pleased to have your comments upon the above limits and also upon the regulators as soon as you have had an opportunity of testing them, in order that any revision of the specification issued to the works in Birmingham may be made, so that there is no delay in executing the order for 50 regulators. Yours faithfully, JOSEPH LUCAS LIMITED. W.R. Robinson Eng.& Designs Dept. | ||
