Hi Joe,
I am so very new to the Danish Modern research but from what I have learned recently, (in my uneducated opinion) the lines look like Kofod Larson. I am even worse when it comes to identifying wood but I think Walnut. I have 2 D.M. chairs which I believe to be Kofod Larson. I found 2 exact sold Ebay item # 180783938742. Mine are also in those "very Brady" colors except 1 orange and 1 gold. LOVE the Danish Modern though and hope to get further educated. I would definitely get confirmation from someone with more knowledge from my identification suggestion.
Have fun in your search and Good Luck!
Marla
