Help!

I have a Magnavox turntable stereo that was given to me 15 yrs ago. I know nothing about this except it's a high fidelity and made in England! I'm afraid to take the back panel off to find any serial numbers! I'd like to sell it but have no idea what to price it at! Radio works, turntable tries to spin but won't, arm still moves, needs a new needle and has some scratches and moisture damage. It's been in storage for about 9 yrs as I've had no room for it! If anyone can help with info or pricing I'd really appreciate it!

First, Magnavox products were made in Fort Wayne Indiana, not "England".
The Collaro record changers used in them were made in England.
Second, "serial" numbers are of absolutely no value, I simply cannot understand why people always seem to think its important.
MODEL numbers are more important, and you do not have to take anything apart to see them - there's a label on the back of the unit, unless it's missing.
However, they too are of little importance in most cases.
As for that particular console, in as-is condition, would go for around 25-45 bucks, and certainly needing a mandatory overhaul/restoration.

That's why I'm asking people who might now because I obviously know nothing about them! And no there is no numbers or anything on the back, only numbers I could find were on the changer where it says made in England. Thanks!
