- Dynamo -

In our memo BY/RD2/DM.{D. Munro}8-3-30 we instructed two Machines to be put in hand of the higher-output type and suitable for use with the Half Charge Control Scheme. One of these Machines is to be fitted to 18-G-4 and it is necessary that it should have our latest type of Die Cast Bearing Bracket and, therefore, we send you herewith a new L.O.P., and Blue Prints of the new parts involved.

For all other features the instructions as issued in the above memo are O.K.

Bearing Brackets. Sec: 8080. D.51895.

D.51839 DC. Bearing Bracket, comm. end. 1 off.
D.51892 Stud, securing Brush Holder. 6 off.
D.51893 Stud, for end cover. 2 off.
D.51894 Clamping Plate Assembly. -
D.51895 L.O.P.

Will you please have two sets put in hand for these machines.

We are preparing the remainder of the instructions for you.
