Quick post to address some of the comments on the previous post:
I now have the Egyptian Revival set by Pottier & Stymus in my possession and I’ve done some digging to see if the upholstery is original and based on a tip from Woodwright to look for tack holes other than those of the current upholstery, it appears the set indeed has the original upholstery (no other tack holes).
I found the “PS” markings to denote Pottier & Stymus under the mount on the skirt of the chair.
I will be receiving two additional mounts shown below and one of the missing feet in the mail shortly. I assume the two heads are from the sofa that is now no longer with us in this world
The red velour fabric is about 50% worn off of the set, there is significant fading or discoloration on much of the original tassels, and one of the chair backs is shattered and will need repairing so I am nearly set on reupholstering, while holding on to the original for posterity.
Much will need to be done to bring this set back to an acceptable state and it will take time, but I hope to bring you all along for the ride as the journey unfolds.
