Need value for Brunswick/Claremont Billiards Table

I have a used 7-foot Claremont Billiards (Pool) Table from the 1970's that I am trying to determine the value of so I can sell it. Does anyone have a source I can go to to approximate the value? I can provide the serial number, etc. Thank you!

I'm no help to you but I finally was able to post and when I finished I looked down and saw you had a similar question. You have me beat by knowing the year though. Well good luck to you
