After further testing this is the pattern. I hope somebody can offer some insight

Dirty number button contacts! The number buttons have two contacts - so, for example, the A5 doesn't work but the B5 (routed through the second 5 contact) does. Same for C5 and D5 etc etc. D8 is an oddball and likely a bad contact - assuming you've checked the coil! - within the pinbank. It's a 5 X 20 matrix in the pinbank, five group relays each with twenty contacts.

Carefully check the wiring on the back of the pin bank! I had the exact same issue a few years ago and it turned out to be a loose or broken connection in the wiring. It makes sense (as if I remember the schematic properly) the letters and numbers are in groups just as described. Every other letter is daisy chained together. Mauro

Check the number switches of keyboard - The second bank of wipers on the keyboard numbers. I think you have a problem with wiper that connects #4 to #5. There should be continuity on two rows of the number switches. You only have one that is complete, the other row has an issue.
I have an image that may help may that you can find here:

Note the circled contacts on the Keyboard Selector - pretty sure this is the problem area.
