Did you do Advanced Third Reich? Currently, that project is owned by @dennis.jorgenson, @tdunnavant, and @uckelman. Are you one of those two first users? In that case, you should probably ask @uckelman to change either of them to your new user name @daddio2 .
Or, did you do Rise and Decline of the Third Reich? Then, perhaps you should try contact Bill Thomson (@wga ) - either through here or via bill@wargameacadamy.org - to see if you can be added as an owner to the module project page. I’m not sure you will have any success, and if you fail with reasonable effort, you may be able to convince @uckelman to add you.
In a fair bit of the modules made by @wga, there are custom classes. Most of these have however been superseeded Vassal proper components. For example, the “look-at” element is now standard in Vassal.
In Advanced Third Reich a custom component of Oblique hex numbering is used. The source code of that isn’t directly available, but you may be able to use one I made - see here. See also Creating Custom Classes.
Which of the various Third Reich modules are you talking about:
- Rise and Decline of the Third Reich 4th Edition (owned by @Buzz32)
- Rise and Decline of the Third Reich (owned by @clanmacrae)
- Rise and Decline of the Third Reich 4th Edition (PBEM) (owned by @maciwt)
- Rise and Decline of the Third Reich (owned by @wga)
Perhaps one or more of these, or older version of the module, contain your graphics.
I think Bill wanted to limit access to those rules - perhaps out of concerns around copyright infringement. But you will have to get hold of Bill to know for sure.
The full clue is:
what some would respond when asked if they are here - in a sort of militaristic fashion - starts with a
pends with at.
I think you can work it out from that
