1953 Royal HHS Typewriter (Polish)

This is a 1953 Royal HHS Typewriter, the S stands for special ordered typeface which appears to be Polish judging by what's printed on certain buttons. It's in good, vintage condition with minimal scuffs around the body. I have pictures of the serial number for anyone curious of narrowing down anything else more specific. Mechanically speaking, it's in proper working order, nothing is broken or loose and all the buttons and controls function correctly. However, the ink ribbon has long since dried out and needs to be switched, it would benefit from a good cleaning since it is dusty on the inside. It's also missing a single key, the letter O, from the keyboard. Because of this, I'm obviously gonna list it for a lot less than a fully maintained or mint example of this model. Feel free to message me with any questions. $80 OBO
