Another unusual opponent for your Prussians could be Hannover. Here is Richard Knoetel on the subject. 1866 Miniatures do some Hannover troops in 28mm. Facebook here
I have about 2/3 of the 1866 Hanoverian army completed. All 1866 Miniatures. Just the other day I was thinking about the great "what if". "What if" The Hanoverians, and the other Federal German States had managed a quicker mobilization and joined forces with the Prussians. I have to thin k the Prussians would have been hard pressed to defeat that unified alliance!
Interesting Dave. If you have any photos of your forces...
I do. I'll collate them and get them to you. I wished 1866 had done the horse artillery. It wouldn't be worth it for them based on sales, but they sure are cool looking! One unit of four would do it. When I return to 1866 in 2022 I may need to convert some.
thanks - be good to see some done
