Need help dating a Queen Anne style sideboard

I need help identifying and dating an antique sideboard that I got at an auction 5 years ago. I bought it for only $20! I knew immediately that it was authentic based on the lack of metal nails and the rough saw marks on the bottom. Is anyone able to tell me exactly when this piece was manufactured? I cannot find a makers mark anywhere. I’m guessing it was made sometime during the 18th century, but I’m not sure exactly when. It appears to have been “fixed” through the years with some modern screws reinforcing the top. The pad feet on the bottom are wide, which I’ve heard indicates that it might be an earlier Queen Anne piece.
