National Furniture Co Antique Dining Set-need help

by Lori Spencer
(Glen Rock, PA)

I have a solid mahogany dining set that has several markings on the underside of the oval table, which is 60" x 48" x 26" high: Stenciled in black on the skirt is:
R NATIONAL FURN. CO.,
JAMESTOWN, N.Y.
The "R" is barely visible from behind the leg bracing and I think there are add'l letters, maybe MFR?

On the bottom of the table top are 2 series of numbers:
4058
6-48 stenciled in black ink

6595/22 written in black grease pencil

Also on the bottom of the table top written in yellow grease pencil or crayon is: "Rusfeld" and there is a paper name plate with the name "Mrs. Rusfeld" hand-written in old script on the other half of the table.

The table has a brass release mechanism to open the table to accept addl leaves, but I was not able to get the leaves with this set when I purchased it 25 years ago. The table top and skirt are rimmed with a bead-and-reel design carved into the wood, not applied to it.

Both the table and the chairs have Cabriole legs with Whorlfoot bottoms. The center table support is an "H" design, also with Cabriole legs and Whorlfoot bottoms, with a turned ball design connecting the 2 legs in the middle.

The 4 side chairs have carved, crested rail backs with pierced back splats. The upholstery is a cream leather or vinyl with brass nailhead detail. No idea if this is original upholstery. I somehow doubt it, but the black muslim covering on the bottom of seats looks to be very old.

I am assuming that this set was manufactured by the National Furniture Co. in Jamestown, NY, pre-1920, when the Blackstone Ave. factory was absorbed by the Union Furniture Co.

Are there any details that anyone can furnish me, including an estimate of value and/or suggested current retail?
