It is a half sheet finishing sander. I have one made by PorterCable long
ago; it is a most excellent machine. They are occasionally available on
ebay and now sell for around $150 and up which is more than the original
price. If your machine functions in an equivalent manner, it could be worth
the same; trouble is, the PC 505 has a reputation, yours does not AFAIK.
