Regency or Early Victorian Mahogany Upholstered Chair

Details:

If I could award a prize for the most inappropriate and ham-fisted mend, this chair would have qualified for an Oscar:
After I removed the car-body filler, bits of metal strap, screws and other bad things I spliced new timber into the usable parts of the side rails so as to be able to replace the original joints which hold the side-rails to the back legs.
(As a rule NEVER use metal screws near the joints in antique chairs because it tends to weaken the joint by disrupting tenons and dowels, making a bad situation worse.) Under all that varnish and grime was a beautiful mahogany chair; notice how the rail between the front legs mimics the front edge of the seat.
The inside of the seat backrail is branded with the maker’s mark, “J.J”. I cannot be sure but it may be the London maker Johnstone & Jupe , known to be at No. 67 New Bond Street in the 1830s.
From the carved crest-rail to the spade feet on tapered legs, this chair is the epitome of classical Regency.
