Design Post Update

At this past weekend's estate sale HERE I purchased a Biedermeier stool for use with my comfy reading chair, another estate sale find which I recently had reupholstered (see that transformation HERE). You can see the upholstery that came on the stool is in good shape, a synthetic material from the 1960s, but doesn't quite go with my apartment.
I have some lovely black mohair I purchased for another project and never used. I worry this is the opposite - too dark.
Some striped velvet left from a chair I recently had reupholstered in my bedroom would work but I'm not sure it works here.
The last choice I already own is an embroidered paisley silk in blues and french grays. I think the colors seem to go with the room, the darker colors may mask any dirt, and the paisley patterned fabric relates to the chair.  I'm obviously leaning in this direction but what do you think, will any of these work?

This past weekend I attended one of my favorite kind of estate sales: a very old Washingtonian family in a very old grand house. The family bought said house during the great depression after selling their huge estate and literally never touched the house again: not paint, no adding furniture, etc.  Shabby chic would be a great term (if it wasn't already attached to something quite different). I wish I had some pictures to share with you of the house but I never thought of taking any snapshots unfortunately.
Sloans and Kenyon, a local auction house, hosts the best estate sales of the oldest families here in town. If they're hosting you know you need to be there! I had a huge haul (including literal armfuls of linens which I spent all day Sunday oxy-cleaning, laundering, and ironing) and just a few of the items are shown here in this post.
One item I purchased remains a bit of  a mystery. This small pitcher reminds me of belleek ware - the collectible paper-thin Irish porcelain, but is unsigned.
Notice it is double walled, the outer wall being pierced with a continuous inner lining.  The only marking is an S.72. and an LS scratched into the glazing. I can't figure out who made the thing.
Any idea who could have made my new treasure?
