Voice of Music record player model #564

Found this player when going through some of my grandmother's belongings after moving her to an assisted living center. Plugged it in last night and the turntable tried to turn but was so dirty it soon stopped. I did some cleaning of the inside workings and light lubricating on the motor and turntable bearing and now it works wonderfully. Needs a new needle(big surprise) but even with the current needle it does play- just very quietly, even with the volume on max. Found the model on thevoiceofmusic.com along with photos of the original with the date of 1959 as the original production date. The only difference in this one and the one shown on the voice of music web page is that mine does not have the 'leg stand'. It is in excellent condition- only a few very minor scuffs and scratches to the cabinet. It has been well cared for over the years. I first estimated it was likely produced in the late 70's to early 80's just by its condition. Would greatly appreciate any help in giving this item a value
