Piper Catalogue Number Help...

Hi... I just bought a Piper at the Gates of Dawn LP (very exciting!) and I'd like to know a little more about it. What I do know is this:

-The catalogue number of the record is EMS-50104
-It is a stereo version of the LP
-It appears to be of Japanese origin (it comes with a lyric sheet in Japanese and English)
-I paid $30 for it in a New York record store and it's in fantastic condition

First up, what is it? I guess it must be a re-pressing, but if anyone could tell me whenabouts it was done, I'd be very greatful... if anyone could tell me a way of looking up info on it that would be just as good.

Secondly, was I had? Did I pay a fair price for it? Maybe (here's hoping) I got a bargain...

Thanks in advance for your help and knowledge!
