My original question was how to date the furniture? What draws you to these conclusions and what evidence do you have? Can you explain your process to get to your conclusion. I have have the advantage of being able to physically examine the table but not the knowledge or experience. The saw makes underneath go at 45 degrees to the wood grain and are straight and not circular saw marks. The screws holding it together are flat head screws, machine made and rusty, not hand cut. The table has been revarnished. The bottom of the legs have holes presumably for casters. The holes are off centre and would not have been used in the turning process. The wood planks used to make the top are of varying width 5 3/4, 9 1/4, 10 /3/4 and 4 1/4. The fretwork on the four legs is very similar with some slight differences but very minimal. The wood between the fretwork is black and and has not been revarnished.
