The chassis has been manufactured inEngland continuously for the last 17 years, and theAmerican product is identical tothe British, not only in design,but in method of construction. Infact, the duplication is so exactthat a well-known American engi-neer who is thoroughly familiarwith American production ma-chinery and methods, when givenan opportunity to inspect in de-tail two chassis, one American andone English built, placed side byside, was unable to detect any dif-ference definitely indicating whichwas which. Our purpose is primarily to de-scribe some features of the chassisand details of construction whichare different or more elaborate than usual. Since the chassis is one of the highestpriced of any produced either in this country or inEurope, it is natural to expect the use of the highestgrades of material and workmanship, as well as elabor-. ateness of design in respect to those features tendingtoward the greater comfort and convenience of ownerand operator, and longer life of the car. The engine has six cylinders, 4V2 by 4% in., cast intwo blocks of three, and with a seven-bearing crank-shaft of 2% in. diameter. The crankshaft is forgedfrom nickel chrome steel and isfinished all over, and the bearingsare lapped after being ground, toobtain a smoother surface than ispossible to obtain by crankshaft is, of course, heat-treated, and it is noteworthy thatthe heat treatment is applied onlyafter most of the surplus stockhas been removed, in order £o en-sure more rapid and uniform cool-ing on quenching. The bearing caps in the crank-case are made of nickel steel, heat-treated, and are held in place bymeans of bolts, rather than studsscrewed into the aluminum. Forboring out the main bearings inthe crankcase, dummy aluminum caps are made use steel caps are ground. The bronze-back, ba
