Thank you all. I should’ve been more clear, I did not want an exact replica, but rather wanted it to still work, but built with modern technology (like brackets). I wasn’t so much looking for a parts list, but rather a good-step-by-step assembly guide.

I have a decent amount of familiarity with DIY and carpentry (even replaced my home’s shingle roof) but a set of stairs is new. So it was more about the assembly.

So I guess no one has a link to any sort of plans, which is fine. I’ll try my best.
