Scientific Angler System 5 by Hardy Value??

I asked on another thread about the value of a S-A system5 reel by the Hardy Bros.
I was curious as to the true value of this reel. It has been used well and is in fair shape. It was purchased somewhere around 1975 by my father. I know the sentimental value is priceless but, I am more interested in the actual monetary value. I do not intend to sell it, just curiosity. I wish I could post a pic but, I don't have a way to do that.It does have similarities to a old CFO type reel.

Thanks,
Rich

ebay is a good place to find the value of items.

I bought one in similar condition about 3 years ago for $110 . It was a system 4 however .
