Meddle US Orig Pressing....pecking order

Did you check discogs? That's usually where I start if looking for matrix
info. I just got a UK first of Meddle, cleaned it but haven't listened to it yet.
PS: check the 1975 US reissue, it looks like that might match yours.
Sometimes, you'll get a mongrel, that has the same stamper or deadwax
info as one identifiable release, on one side, with something completely
different on the other side, that doesn't seem to match a particular pressing.
For example, I just got yet another Monarch pressed copy of LZ1 that has
the AA 'RG' info on side 1(corresponding to a US first) , side 2 is something
else entirely!

Get Japan first issue. The sound is sublime. I have UK and I like Japan a bit better. You can get a mint Japan, probably not UK. That could be the reason I like my japan issue a little better.

Better, Viridian. I had forgotten about that site, now that I've been buying some of the other Floyd albums (apart from Dark Side and Wish You Were Here), it is helpful to me. Thank you.
