On one of the shows about the Simplex Modular Mountain Retreat Home Project, Bob was mentioning the interior door hardware which I believe he said was from M Tech. I wanted to know if this is the correct name and if they have a website to view their products. I would like to purchase the interior door hardware that was used in this home. It is a 1920's type door handle. The knob was a glass knob and the base was a nickel finish. I'd really appreciate the information.
