My LED ZEP 2 pressing anything special

It's one of the good sounding releases and definitely worth keeping, but it's 1977 re-issue according to the information provided.
The first US pressing was Sterling mastered. It only compromises to the first UK issue sonically, but outperforms any other re-issues including MOFI, Classic and current. Listeners that value more quiet background will certainly like Classic records re-issue. To me it's missing lots of sound I can hear in first press.

Wow, I stand corrected. Went on Discogs some time ago, and somehow came away thinking this was a first press. The first US is 1969, and as Czarivey says, is a 4 digits. According to my fresh look at Discogs, it's SD-8236. Now I will be out there in the back alley vinyl shops fighting for my copy. Touche gentleman (-:

Fjn- the George Piros (GP in the deadwax) copies should be pretty good- his remaster of LZ1 from the mid-70's is really excellent. Short of finding a clean, unmolested copy of the 'RL' of II (which is expensive even for VG +or- copies and not easy to find) or the first UK plum (which is nutty money), you should be able to find a nice GP for reasonable money. I haven't listened to a GP of LZII (at least to my knowledge) recently, but in the shoot-outs we did of LZ1, the Monarch pressings were also more alive than others, US or UK. So, one possible short-cut is to find a GP/Monarch of II.
Good luck, and let us know what you find in the bins.

So, just for clarification, is the original UK on a par with the US RL, or is it even better.

I have the UK Plum and Orange first issue in NM- condition and RL in EX condition. If I had to pick between the two, even if the same condition, I would keep the UK. Happily I don't have to make that decision. They are both great in their own way.
