Wanted! Copy of Spitfire Modification 1323 that details the removal of the Thermostats from the Spitfire Mk. IX cooling system.

This mod. was issued in 1946 to delete thermostats from both Merlin and Griffon powered Spitfires which had engines with two-piece cylinder blocks.

I have the Mod. for the Mk. XIX but need it for the IX as the  pipes are different and not shown in the parts manual.
