Al, I've just had a look at the runout grooves on my copies of Blues if Desperation and Black Coffee, and other than the album number, they both have MPO, with what looks like a reversed 6.
B o D also has SSO. MW etched in.
Don't know if this helps identify the pressing plant.
Oh, I have the red vinyl.
Thanks, that's useful. MPO is usually one of the better pressing plants, but I guess nobody's perfect!
The other marks might be a mastering/cutting engineer's signature, but that won't be the person to blame for a warped disc. Are you sure it's not 'SST MW'? That's an engineer at SST Brüggemann mastering house in Germany.
I know this stuff is super-nerdy, but it can be helpful in knowing which plants to avoid and which give the best results, as sadly with so much expertise lost over the past 25 years, mastering and pressing quality has become a bit of a lottery.
There's a really useful list of common runout etchings on Discogs, which is what I refer to.
Anyway, Al, I hope your next copy is in tippy top shape and gives you hours of listening pleasure.
