Something I’ve been wondering about the 6 needle telegraph encoding is if it was ever actually designed or built by cooke/wheatstone. The only reference to it I could find online is Wikipedia saying that a six needle code ‘could be used to encode 30 characters’. However was this design/idea ever actually used, or if its more of a historical-stretch of the 5 needle used for the challenge so you can encode the full alphabet?
