Yes, it is BBC. I have an MN6/502 oscilloscope with a general purpose amplifier module AM5/518/105. Many years ago I wrote to the BBC and they sent me the circuit diagram of the scope, but not the plugins.

BBC white module kit is usually very good. I've got two PAL colour coders from the same era and both are still working, albiet not perfectly but the are producing encoded colour
