To expand upon Madness’s excellent explanation of my final method, I thought I would add this regarding how I found it:
One of the key ideas that drove me towards a solution is that in the ciphers used here, it is typically the case that every pattern and detail is important and should be accounted for, not ignored.
How very gratifying! Harry
That got me as far as the numbers 0-35 and 0-15 as it helped steer me away from some of the blind alleys I went down. From there the final steps to solve were generally more apparent (in a relative sense) than the previous ones as it was a case of generate text based on a hypothesis and test the resultant text, especially once I had the realisation how to split them up…
