Two manufacturers are represented - Marvin and Eagle. Because tooling up to produce the windows is extremely expensive, each has brought a sample window, nearly but not exactly a copy of the replacement. My comments address the issues I thought prevented the windows from being exact enough to be approvable. You may have additional issues. Representatives of each manufacturer will be present to answer questions about whether the exact duplicates are possible in these materials.

Eagle:
1) The window stoops are too small and have obvious piecing.
2) The horizontal beaded molding that separates the window from the transom is not an accurate reproduction of any of the courthouse windows.
3) The lugs (shaped pieces at the bottom of the upper sash) are too small.
4) The top window sash rails on each side should run the length of the sash with the lugs a continuation of that line; the top and bottom rails should be butted into the top rail.
5) The muntins in the transom should be wider and deeper to reflect the dimension of the existing.
6) The pattern of separation in the transom should duplicate the original.
7) The hardware, including pulls and sash locks, should replicate the original in size and weight, and may be reused from the existing windows or may be new.

Marvin:
1) The window stoops are too small and have obvious piecing.
2) The horizontal beaded molding that separates the window from the transom is not an accurate reproduction of any of the courthouse windows.3
3) There is too obvious a line visually separating the lugs from the sash.
4) The top window sash rails on each side should run the length of the sash with the lugs a continuation of that line; the top and bottom rails should be butted into the top rail.
5) The muntins in the transom should be wider and deeper to reflect the dimension of the existing.

In addition, it should be determined whether the metal framed windows can be reused.
