another mystery to me chair  

Hi all. Here's my birthday find today. Love it, but I have no idea who made it or designed it. Don't care what it's worth 'cause it's staying here. I'm in the process of making a bottom cushion for it now.

I'm just looking for some help with an ID. Reminds me of Larsen, but there's no Selig tag(or any other tag). Only marked with a few numbers written on the bottom with a black wax pencil.

I just can't find anything with an attached back like this. I don't think it's US made either. Too heavy and well made, and flows too well.

Any help would be appreciated all!
