I don't have 'Original Punks' or 'Penetration' but I do have 'Rough Power', so perhaps the following may be of interest.
The first eight tracks are stated as being the "original Stooges mix" of 'Raw Power'. In my opinion this is nonsense. The tracks are certainly different, but the 'building blocks' of these mixes are pretty much identical to the finished Bowie versions. We can only speculate as to their actual origin. However, bearing in mind that these tapes were given to Bomp Records by James Williamson, it is likely that these are Iggy mixes copied to James as an example of how the album would sound. Possibly the same mixes that were rejected by Mainman/Columbia. There is an often-told story that Bowie mixed the album largely how Iggy wanted it to sound, so these tapes would seem to fit with that story. It is also possible that they are rejected Bowie mixes that somehow came into the possession of James.
The 'Complete WABX Broadcast' is a disappointment. It is obviously put together from different sources ('Hard to Beat' and 'Death Trip' have ludicrous pitch problems) and is in mono. It is also not the best available quality.
Not much I can say about the final three tracks. Obviously different mixes, but heavily tampered with (EQ etc). 'I Need Somebody' sounds like it has been played through a cheap hi-fi system and re-recorded from there.
Anyway, I hope that helps.
