Strangewings translated these titles a few years ago, & he is still learning Japanese. I might be wrong, though; it could be he merely transcribed the title, & google translated it.
edit: I just changed the title to your translation, so anyone who wonders about your post, Crazy_Red, will know why.
I just ran 'もう一人の美理' through google, & it comes out "Physical beauty of another"; I know "Physical beauty" is Miri, & there is no need to tell you that the phonetic translation is "Mōhitori no miri."
I had no idea about the prototype body; though, I thought it was funny they were on hangers in a closet.
This scene reminds me of MCHALE'S NAVY; I guess it was the 2nd season, when they were stationed in New Caledonia.

McHale & his misfit crew had an underground hide-out where they hid everything they wanted to keep secret from Capt. Binghamton.
This reminds me of ROBOT HOUSE, in which suction cups were used against Atom.
The villainous Nazi-types are in for a surprise, because Mars was the decoy!
I know I have seen an anime in which the cute girl's fake head doing the eyelid tug tongue out [I forgot the word for it

] Jack-in-the-box.
What is with this flying saucer? Are Salome & Seshimo extraterrestrials?
A plug for ROLLS-ROYCE.
I did not think Mars was particularly strong, until seeing this.
Crazy_Red,
is this the guy's brain? I can think of no other explanation, but that.
So ends this episode.
About the name: I was certain I heard 'Sal-o-me' L/R thing not withstanding.
