Torpedo color ?

Tnx for the advice, and yes you can post picture on the forum, but they have to be hosted somewhere else (personally I use www.photobucket.com), than you type [ img ] url of the picture [/img ] but without any spaces, neither in the brakets nor in the url.
You say the later version had a steel outer skin, so I suppose the torpedoes on my S7 would have been bronze ?

Live KM warheads were painted gray.  Practice warheads were red/white striped. According to  Roessler's book on German Navy torpedoes, the outer skin of pre WW2 torpedoes was bronze, later versions was steel.  

Is there some way to post pictures on this thing?

The Revell S-100 instructions specify the warhead of the torpedoes as a copper/bronze colour, and the fins in dark grey.

Yes, indeed, it will be the good old Airfix "E-Boat", going to buid it for the Kriegsmarine GB.
I guess, I'll try to simulate some kind of "oily" bare metal (I figure, if they were bare metal they've must have been oiled to prevent corrosion).
Getting me to another question though, would the explosive warhead have been the same color as the rest of the torpedo ?

I was wondering the same thing for the S-100! Sorry I can't help. The instructions for the S-100 kit specify unpainted metal for the torpedoes, but I'm not sure if they're accurate.

Is this the Airfix 1/72 S-7 kit that you're building?
