1973 Queen I - Matrix of the very first UK vinyl?

Hi everybody!

I like to request your help. Can anybody tell me, what the real very first matrix of the first UK press of Queen I is?

I found information on the web that it is:

YAX 4623-3U KIP - HUGGYPOO KISSY
YAX 4624-2U OFF WITH HIS HEAD

And I found other information that it is:

YAX 4623-3U KIP - HUGGYPOO KISSY
YAX 4624-3U AGAIN!

So which one is right? Thanks for your help!!!

From what I've read, the first example is the first pressing, and the second example is probably the second pressing.
