Hart to tell the money for the Army had to come from the states after Article 62 but i am sure if that was changed with later laws
I haven't found any updates to Article 62 either. Those 225 thaler mean 675 Goldmark per head, but that only seems to apply to Fortdauernde Ausgaben - continuing expenses. One-time expenses for new barracks or equipment had to be haggled over with the Reichstag. Looking at 1890s Reichshaushalt-Etats there are numerous instances of requested funds being either denied outright or heavily reduced.
