@Jonny69 you know what you're talking about, any advice? Do I just poke through the "Builders" section until I find something similar or is there a sensible process to go through?

Pretty much just that. You’re looking for the combination of the lugs and any way they have been filed to a custom shape (‘fancy lugs’) as this was usually unique to the builder. Also look for any frame numbers on the BB shell, rear dropout or fork steerer.
