Civil War Military Dispatch font identification

I'm trying to find out what fonts are in this printed military dispatch stationery, especially words in the fill-in lines "Hd. Qrs.", "o'clock", "M.", "186", "To" and "No".

I have searched through hundreds of script fonts but none of them have that capital "H", "M" nor "N" or even that lower case "d".

It actually doesn't look like a cursive font as the letters seem very upright. It's a really interesting and different looking script font. I wonder where these were printed, or if the fonts in printed dispatch stationeries varied depending on the print.

Thanks for any help.
