I am looking for the furniture style (Sheraton, Duncan Phyfe, etc) and an appraisal. There are five chairs all with original finish, and reupholstered seats. One chair has a broken back splat that's been glued together. I reupholstered the seats myself, and when doing so, found some weird markings on the seat frames. They look like a stain that's been blown out with air. Each chair had the mark; I included pictures of two of the markings. Otherwise, there were no maker's marks or imprints. I also included a picture of the original upholstery and the webbing after removing the upholstery.
Wood (unsure of type)
On the chair seat frame, there is a curious mark that looks like a big drop of stain that's been blown out with air.
