Just did a search 'teleprinters' on ebay. Was amused to find a copy of the RSGB Teleprinter Handbook in the "fiction-genre fiction" category. Then spotted "723 Mechanical Teleprinter Patents on CD-ROM" in "militaria - Civil War 1861-65 - other Civil War-Related items" Didn't think we had been around THAT long! Cheers, John GW4SKA
