The armor plate shoulder pads, and "sleeves" (photos C and D) came from the Destroyer costume. Underneath the Destroyer shoulder pads, were also the shoulder pads from his The Elder costume (most noticeable in photo C).
Another difference between this version of the costume and the later revisions, are the Destroyer shoulder pads. On the later versions of the costume, the shoulder pads had padded edges, which this version hasn't. Also note that there's no spikes on the left shoulder pad (photo C). Also note the piece of chain hanging from the same shoulder pad.
Like on the Destroyer costume Gene had spikes on the back of his hand (seen in both photo C and D). These also quickly disappeared. The boots were the boots from the Love Gun outfit at this point, but that wouldn't change to begin with. Photos E to H shows the second version of the costume. Note that the shoulder pads now has padded edges, and that the codpiece now has a different cup... seemingly attached on top of the original. The new armored "sleeves" are very similar to the first version, but there are some small differences. Note that the spike on the back of Gene's hands has now been moved to the cuffs, which has also gained a row of pyramid shaped studs in the bargain!
While both photo E and F shows the second version of the costume, picture F shows a revised version. The main difference is a piece of chain mail hanging under the left shoulder pad (circled in)! The version seen in photo E was only seen at the Creatures Of The Night press conference (ca. October 1982).
The big chain hanging across Gene's chest in picture E, is not a piece of the costume, but a special guitar strap used for the "I Love It Loud" promo video, and several TV appearances during the promotional tour of Europe in November 1982. The strap is also visible on picture G!
As said the boots used with the first and second version of the costume was the Love Gun boots (picture G, detail in picture H).
Picture I shows you the
backside of the second Creatures costume. It's a little difficult to see, but it
gives some idea what it looked like from that angle!
During the Creatures of the Night
tour (or 10th Anniversary Tour as it was billed) Gene changed into a different
version of the costume (pictures L to O). Photo L shows the basis of the second version of
the outfit. This one had a body suit with sleeves, and chain mail at the elbow joints,
under the armor parts.
