I have this one. I thought it had a model number like 900 or something. Its been in my garage collecting dust. Missing the front cover IIRC. I do need to part with it. It was clean when I got it but I was negligent and it is no longer so clean.

I always assumed a newer stock ticker from Teletype would be based on the 28 tape printer.  I was wrong.  Looking at http://www.navy-radio.com/manuals/tty/jh/bsps/bsp/570series/573-140-100TC.pdf, I discover a different approach..  It's a 6 level 135 baud device the uses a type box instead of the wheel like on a normal tape printer.  Also it types on 1" tape.  Of course it has fractions as well as some other special charters.

Wonder if anyone ever saw such a beast?

John, W9DDD
