Hey, I have almost "all" icons for the Swedish tree that I made for Millenium Dawn (I was working on a similar mod like yours) I can send them to you thusly making the Swedish Armor Tree finished.

The vehicles I have drawn are:
Strf 90, Strf 122, Strf-144, Strv. 74, Strv. 121, Strv 122c, Strv. 142, Tb 180, Lkv. 72, lkv 91, lkv 91c, Ikv 113, L-182, Scania R-500, Strf 90, Strf 90/40, BV 206.
In WIP I have:

OMC Galten (wheeled infantry support vehicle)
Patria IFV (Wheeled Infantry support vehicle)
BKAN (Tracked Artillery vehicle)
Archer (Wheeled Artillery)
Strv 1033 (Centurion tank)
Strv 103 (Swedish "S" Tank)

Note: Strv 74 should replace the L-60 tank, as it was what Sweden actually used at the time.

I sent you a friend request, If you like them you can use them, if not no worries. Just trying to save you some work :)
