Hawker Typhoon Harness Release Mechanism

I don’t suppose anyone has, or knows where we can obtain the housing for the Sutton Harness cable release control group:
P/No: A.96842, c/w P/No: A.58847,(Housing for Locking Pin; and P/No: A.96666, Pulley and Harness Anchorage Plug Housing)?
It is needed for our car door Typhoon 1B restoration.
We have the return spring tube and mounting; are about to begin re-engineering the cable pulley tubes and assemblies that attach to the Head Fairing; but are stuck on the release housing.
This housing component was also fitted to Hurricanes.
Copies of drawings for these components would also be of considerable help.
This is the component assembly taken from the A.P.
