We installed , new canopy on the old steel.they wanted to keep as much of original for historical purposes. The window crew was from Ohio, plaster crew from Boston. Each pane of glass 1/4 in. Specially made in Japan, with special gas inside for sunny side or shade side of building. $80.00 per pane , over 1,800 pane. Took 2 yrs to get and they had accidentally broke about 12 at that point.
Should have taken more pics. Of marble floors.
