It is an interesting chair. I don't think it is Danish or American, or at least not from the early 50s to 70s. The only context I have for horsehair is that of a earlier period. I don't know anything about copper springs.
And lastly, the wood does not have the classic appearance of walnut. It is perhaps a little too light brown. Of course, photos can lie, and walnut can be that light. (If you thought it was useful, you could do a smell test to prove it is walnut).

let me know if you need...

extremely good looking chair that I would love to have under my desk. Completely doesn't ring a stylistic bell, though..hum

Kind of a shaped up refined post arts & crafts banker's chair...nice contrast-capped legs there.
The X stretcher's pretty clunky though, it's not too shabby but not worth spilling blood over
I'd guess that it was made by some company with a name like "Monarch Furniture" or "Acme Something or other" or "Good 'ol Boy Brothers of X-burg"

hum
I think it's more refined then that, but I'm not that refined
I was also thinking it had very arts & crafts kind of vibe. if I get any time this PM I'll see if I can come up w/ anything
