X.3348 MORGANITE BRUSHES FOR GOSHAWK MOTOR
X.4384.

Morganite C.M.3 brushes ordered under D.1564 and originally meant for Gos.1 are .75" x .3" while those ordered under D.50228 are .75" x .312"

Moreover the pigtails on the first lot are an inch longer.

It is thought that they would be too loose in the holders and therefore if not used experimentally would be scrapped.
