chair with vague elements of Juhl or Wansher  

One cabinetmaker who frequently used this kind of feet was Peder Moos, by the way.

As per my views, I would suggest you, consult some professional manufacturer to get the clear idea about the chair. The picture of the chair that you have posted seems to be really unique. Contacting people like office furniture solutions ( https://www.officesolutionsfl.com) who have deep knowledge about furniture can also help you to gain knowledge about the types of woods and furniture. Hope my suggestions help you in clearing your confusion.

Just figured out that Klint's safari chair has the same kind of feet too.

Thank you Dr. I won't retrieve this chair but I'm happy it has raised the discussion about the feet, which probably was new to the forum.

Cheers
