An Adler Tessy typewriter in vintage used condition.   I used one of these some years ago. Nothing appears to be broken.  The platen is in used vintage condition.   Paper rolls in well.  The letter “a” sticks when used, keys need a clean.  It will need a good service as the machine is grubby and dusty.  The ink on the ribbon is faint.  Dont hesitate to ask any questions.
