EAC.10. STARTER MOTOR.

Please find attached blueprint of
LeC. 2517. which should clear up the remaining doubtful
points on the above.

I am sorry that this matter has been
delayed, but was just dealing with it when I went off ill.
Some re-arrangement of the proportions
has been rendered necessary to accommodate the armature
and field windings.

At the same time we have included a
modification which allows us to use the standard Bijur
Drip plug.

The motor end cover has been cleaned up
to render it a simple die casting.

E.{Mr Elliott - Chief Engineer}
