D. {John DeLooze - Company Secretary} 50199 General Arrangement. Regarding the Ballast Resistance Wire D.50197 it should noted that this is the same gauge as used on the 40/50 Chassis Ballast Resistance (see F.7361) and for experimental purposes F.7361 can no doubt be coiled to suit. To have a reasonable clearance between each Coil of the Resistance Wire and to follow out the design as shewn on LeC 1410 it is only possible to have a length of wire 32.5" whereas the length of the 40/50 Resistance wire is 50". This matter has been taken up with EFC {E. Fowler Clarke - Electrical Engineer} who has written to R concerning this and until such time that we hear from West WitteringHenry Royce's home town D.50197 should be used. BY {R.W.
