I am building a G7e torpedo now. Is this thread has been up for some years and many links to pictures are broken and also files that has been shared (I guess with good info on colours on the different mods/models) do I wonder if someone could help me with the colours of a standard G7e/T2 or T3 torpedo.
In principle, there's no visual difference between a TII and TII besides the text "TII" or "TIII" painted inside a ring on the forward part of the batterychamber (this was not always applied though). However, if the TIII were fitted with Fat or Lut mechanisms, there would be several issues to distinguish it from a TII.
-
- War head: Light grey / Dark grey (Depending on T2 / T3 - It would seem that a darker grey is most accurate either way.
- Igniter: Brass - The pistol was made of brass initially, but they switched to steel during the war (painted grey). For a TIII the latter would be more correct
- Body: Silver - Unpainted steel
- Aft part: Light grey - Unpainted steel
- Propellers: Silver - Unpainted steel
The steel hull would have been covered in a protective grease giving it a brownish/golden tint.
If it can help, it is for a late war (1945) Seehund sub.
That's another story... It's clear that the Kleinkampfverbände painted their torpedoes in order to obtain proper camouflage, both for road-travel and in water - even with a camouflage pattern (as can be seen in certain photos).
I have no idea if this was governed by regulations, or left up to the kommands theirself to decide in terms of colours and pattern. My best guess would be shades of dark and lighter blue and/or grey for the hull and propellers.
