I came here to ask the same and I think i figured out the answer while watching, haha. I believe he first used a varathane pre-stain conditioner (only appears as stain here since it is wet and being absorbed to balance any natural wood variations) and then the 2nd *actual* stain is General Finishes gel stain in antique walnut (can see part of the word antique on the can and that shade is very commonly used for mcm pieces, lol). I also looove using general finishes gel stain in candlelite for a lot of mid century pieces. It warms up the the woods for a perfect rich “glow” without being seen as RED or YELLOW. Perfectly natural and warm. All of their gel stains are very easy to use. (Candlelite also seems to match a TON of original finishes quite nicely when you might only be sanding/re-staining a smaller leg or maybe only the top of something?) This comment is a year later, but maybe it still helps someone? 😂
