I may be a bit optimistic dating this chair at 1799 or before. But the oxidization of the wood on the inside is excessive, Square nails, The wood is cement like, and the small size. 21" wide in the front and a mear 34 inches in height makes this chair one seldom seen. And sure was created before 1840 imho.
All the joints were tight after disassembly except this one I glued up & clamped.
The wood was pretty dry till I applied a coat of this fine restorer.
The bottom base was completely stripped, regaled & new screws, set at the same angles as the main frame.
Then traditional webbing set just firm enough.
Hand tied coil springs, inspected & reset.
Then traditional burlap with nosing.
Quality 2635 foam custom cut with full coat of cotton.
And lined before upholstery fabric.
The inside back frame was completely stripped as well. Some parts of the frame glued up also.
The horse hair was saved on the inside back with fresh cotton & lined.
Matching traditional gimp on the outside back.
What a nice crown with the sufferings married up to it nice & clean.
This small tight frame is ready for another round in the world.
Thanks for looking here!
