SpectreCodename for Phantom III Gearbox.

We send you herewith N. Sch. 4091 which shows increased lightening of one of the speedometer drive pieces and also asks for a L.H. thread for the spiral gear nut.

We also send N. Sch.4093 to show how clearance should be provided for the 1st speed wheel and how collar nuts on the I and 3rd S.M. split sleeve will give clearance for the reverse gears.
