Just found a terrific website for a terrific company, Crestview Doors that specializes in making doors for mid-century homes. Love It, Love it! They are located in Austin, Texas. Their website showcases a lot of mid-century design, including a picture of my living room at 130 Krog Street (so you see, I know they have great taste).
Back in 2003, when I was restoring the historic Wigwam Building, I spent a lot of time and money restoring the existing doors which when done looked good but still had some lamination issues. I may have been better to have them copied. Crestview doors seems to be a company that can do the job and knows their stuff.
