HEAT SHIELD FOR EAC. 7. X.7230
SILENCER. X.3908

We thank you for your sch.915., and although we
agree that it would clear the various obstructions, we think
the brackets should be flexible in the longitudinal direction
to allow for expansion.

We therefore suggest on N.sch.2412., (herewith)
that they should be fastened to the forged flange piece
itself, suitable platforms being formed on this either in
the forging or by welding. We think the strip brackets
bent out of the square should not present any difficulty.
