Thanks Ogre, I am quite familiar with the teletypewriter type machines and I was at one time quite skilled in their use however the typewriter I was shown was a manual typewriter but interesting for its light weight and the fact that it was quite like what we used to call a "Signals Typewriter" which was optimised for use with Morse Code. Of course the notion that it was a relic of those golden days of the Clipper boats gave it an extra aura!
I believe the Signals Typewriters we used had very heavy cast steel frames and the finest that Mr Imperial could make!
