To Order No. Customer's No. With regard to the above, the distributor is of good design and we consider it to be superior now to the B.T.H in the following details :- a) It is not cut away considerably to accomodate the contact breaker housing thus making it less susceptible to contraction without the addition of a thick dome. b) In spite of not being cut away it is 3 oz lighter. c) It has a better finish. We consider however that the provision of three extra ventilating windows in the head is unnecessary Signed contd This Sheet must be filed on completion of the work. | ||
