Will you kindly arrange to let us know the capacity, in microfarads, of condensers as fitted to the following chassis, with plus and minus limits:

Handwritten notes on left margin:
Long Bore D 54808
double bore D7546
short D75462
Tcc!

Main List:
Tcc Bentley (2 types) - 59 on E series
tec Phantom III (1 type)

Tcc { 25 H.P. - - 15.10 - 31. 101
30 H.P.

and also for Watford EO6 and EW6 magnetos.

We have recently installed a condensimeter for testing the capacity of condensers and the above information will be very useful for us when testing condensers.

Sr/VA.
