I will be happy to help with your assessment, however I only handle one item or matched set per question here. Since the sofa image is attached, would you like to continue with that on this question thread? Also, can you add some images of the surface detail on the wood as well.
My apologies, I had to step away from my computer for a short bit. Thank you for the images, please allow me to look them over for you.
The dining set is a marriage or pieces and not a matched set that were original to each other. Please note that I only assess one item or matched set per question here. The sofa, buffet, table, and pair of chairs (that are a matched set) are 4 different assessments. Please choose one and let me know.
I can certainly help with the chair set. In order for me to properly assess them, I will also need to see a full image of the back of a chair and a clear, well lit image of the underside of a chair.
Get Well Soon and take it easy. You can send it over at your convenience, there is not a time limit here.
Thank you for the additional images. My apologies for the delay, this was lost in a shuffle for some days.
Please allow me some time to look everything over for you.
Thank you for re-opening the thread.
