1 1/2 VALUE BALLAST RESISTANCES

Will you please let us have the two standard ballast resistances which were replaced by the two ballast resistances of 1 1/2 value which we sent to you for test.

We desire to return these to Mr. Brock in order to obtain two further 1 1/2 value ballast resistances to replace our stock.

EFC.

Reed.
