Sunderland production line
When doing Tucano groundschool in the late 90s, we were told that the cockpit lighting rheostats were so remarkably large because they had been taken from the Sunderland spares bin lurking somewhere at Shorts factory. When MFTS comes in, one could perhaps save on the development costs of 'Sunderland 2100' by robbing said rheostats from retired Tin Cans and redistributing them to our new MPA...and yes it would take till 2100 to re-invent that venerable wheel...
