SpectreCodename for Phantom III and Wraith Gearboxes. N. Sch's 4345/6 herewith show 3rd motion shafts for the above gearboxes with strengthened flanges for retaining the 3rd speed wheel. In the case of the SpectreCodename for Phantom III, if there are any shafts and sliding pieces made to N. Sch.4232 (as instructed for the 2nd box) they will no doubt be quite suitable for ordinary road use, but for long period dynamometer testing the shaft with strengthened flange should be used.
