How the joints are cut is a give-away - were they done by hand or machine?
My dad doted on an old Welsh dresser they'd had for years, and thought it was worth thousands, but sadly, we found the top wasn't a match with the bottom, and the drawers were all machined joints...
We got around £300.00 for it at auction, so that was that!
I'd be interested in your gate-leg table, as we have one given to us when we were first wed, and used it until the family came along, and we needed a bigger table!
