Tempos ~ Countdown ~ Canterbury w/d . . .with issues

[Soulgalore]

Here's the good news . . . it's a beautiful looking promotional copy (same track both sides), visually M- condition. 

Now the bad news . . . both sides either 'skip' or 'stick' part way thru' play.

I've examined the playing surface but cannot find any flaws to explain this ???

You may be able to restore this to a playable copy, alternatively it's a nice copy to mount.

So, I'm open to offers for this one.
