Smith Corona type writer - $200 (Allouez)

Fully functioning Smith Corona Silent type writer.
Serial number places the manufacturer date at 1947.
Could use a cleaning but overall excellent condition.
This was my mom's friend's type writer and I was told it has very little use.
Comes with manual, extra ink ribbon, cleaning brush, and some additional paperwork.
Asking $200 or would consider trade for vintage stereo equipment.
Just let me know what you have.
Thanks!
