I bought a reproduction curtain tray from Antique Auto Sheetmetal in Brookville, OH about 3 years ago. They are owned or somehow related to Brookville Roadster. I have 2 original curtain trays, but they are too far gone to restore. The curtain tray I bought was the correct size, however the three stiffening ribs were not shapped or placed correctly. If you are not a purest, the standard tray they make would work, but I didn't want a bad reproduction. I returned the tray to the maker and had them make one without the stiffening ribs. I gave it to Will Cronkrite at Hershey 2 1/2 years ago to stamp the correct stiffening ribs in the tray with his PullMax tool. I gave him the correct shape and placement of the ribs. He did an excellent job making the correct ribs. The tray is extremely close to a duplicate of the original tray is have to compare it to. If you need a picture or dimensions of the tray or ribs, let me know.
