3. Attention was drawn to the fact that
so far none of the engines coming under S.B.A.C.
Group III had been installed in prototype
aircraft in power plants to S.B.A.C. standard,
neither the Avro "Manchester" nor the B1/38
Rolls-Royce Vulture engine plants being inter-
changeable with each other or with the S.B.A.C.
standard.

It was agreed to approach the Air
Ministry regarding their intention to introduce
the S.B.A.C. Group 3 standards and if so, when.

4. The Bristol Company produced drawings
of the detachable panel for pipes to be applied
to Group II and Group III schemes. It was
pointed out that the Group II scheme is applied
when a separate gear box was fitted, but that
the panel would be universal for Group III.

It was agreed that Rolls-Royce would
check whether the Bristol design could be applied
to Rolls-Royce Power Plants.
