The Nexus download site has a rather extensive list of M&B mods, as well as mods for a bunch of other games. The one link here on the Europe 1805-II sub-forum uses that source, or you can go there directly and browse. Incidentally, I spotted a couple of mods there for M&B which no longer seem to be available through the Taleworlds file repository (file not found error).
Hint- search by game to narrow the list down to mods for your game. You can then either sort by number of downloads, ratings, posted date, alphabetical order, or other criteria. Unfortunately, that site tends to mix the original M&B and the Warband mods, so you'll see both in the lists.
PS - I don't understand the reference to "Hungarian tanks" and "rivets" in the signature lines of the previous post. Most of the (Swedish-designed) Hungarian tanks (Toldi I-III) were of mainly welded construction (including advanced features such as torsion bar suspension), and the few self-propelled guns (Zrinyi SPG, technically not a tank) and tanks (Turan I-II) which were partially of riveted construction weren't that different from Italian, early British, and several other armored vehicles of the time period. Is there some obscure joke to this?
