Friction - here is all what i found for Your projects...

- info about colours
You have probably all those photos already

.
''...*EDIT* Me not having the ability to leave well enough alone, I did more research. That second picture that Lutzow posted as U-33, well it's definately NOT U-25. The U-25 was a type IA U-boat (which we all knew right?), which resembled both VII and IX boats, but more so the IX because they lacked saddlebags. In that picture of "U-33" you can clearly see saddlebags. So, I'm using IXB as a base to try and stay as close to historically accurate as possible. But again, I'm at a crossroads as to use the "U-33" camo pattern or use the pattern that I have in 2 pictures (rather plain compared to the conning tower.) Opinions please!?...''
My opinion is that You have U-25 and U-33 camouflages to reconstruction, because Kaleu L Dog posted 2 photos of two different subs - so You catched two works instead of one:rotfl:.
I will be happy when You make them both for VIIC type - my beloved type.
Of course - this is just my wish

- You are skinner and You decide.
Good luck,
Friction
