| DERBY (7728). B & S (D) 2500 EXTRACT FROM FHR1/H181212. Dated 18th.. Dec. 1912. RE REPORT ON CHASSIS 2100E. Mr. Swift's suggestion in paragraph 3 is good. With regard to the weight of this axle, we ought really to weigh the parts which have been changed in design to find the real proportionate saving and not include parts that we have not attempted to save upon, i.e. the parts altered compared with the parts not altered; 32 lbs. is well worth having.
