I don't have much to add other than to say Great Find and Welcome to the forum!
Certainly will take a lot of work and hunting/fabrication to put it back together. It's true that many of the very early frames were constructed out of solid metal by blacksmiths. Tubular frames and hollow forks were introduced in the 1870s (according to Bicycle Design by Tony Hadland and Hans-Erhard Lessing, MIT Press, 2014); I'd guess what you have is at least that old.
The rear "fork" appears to have been taken quite a blow to be so far out of alignment, no?
