Hi everyone again.
There is a new updated version of the Test Card Disc which can be downloaded from the URL below:

In addition to what was on the old disc, the new disc contains a newly recreated version of the original 5:4 Test Card C as well as a slight modification to Test Card J and a new 1950s BBC Tuning Signal.
Thanks everyone.
Kind regards.
From Mike.
