Marconi wagon mounted Wireless sets were sent to British forces for Boer War. They could in theory have sent radio fax (wired fax dates from 1851!) or 22 line Nipkow disk (like Baird TV) TV from South Africa to London. It would have needed some repeating stations, receiving on to recordable 78s (which may have existed) or Edison cylinders and retransmitted.
Some home recordings of Baird TV exist on 78s intended for home recording of Radio. The Baird tests started with AM radio after hours. Some of the USA AM stations had radio fax transmission in early 1930s after hours as well as the USA version of Baird TV.
Nothing unique or innovative about early Baird systems. The later ones overlapped superior RCA & EMI electronic TV.
