Some images which I hope help.
I attach a quick render of your table with the European Walnut timber, which after reviewing some options, looks the best in aesthetics (in my opinion).
If you prefer the Neva chair (with arms) I would recommend making sure they would fit properly with the Apron on your antique table top.
Older tables can also tend to sit lower than modern day table tops and therefore our chair seat heights should be checked with your table.
A safer option could also be selecting the Neva Light chairs (without arms).
Hope this helps,
