Good catch, Jean-Franco. It shows a minor shortcoming with the original plan. The front and part of the sides of the lower case have an applied molding along the bottom. The plan calls for the molding to be made from a 1-in. x 1/8-in. piece. But that molding interferes with the way the legs fit into the case. So for the purpose of the model, I decided to ignore the bad fit. If I were building the highboy for real, I'd add thin pieces around the blocks where the legs fit.
And thanks, John Msrk Power, for the nice words about the escutcheons. I modeled them after drop pulls offered by Horton Brasses. They were the closest I could find to the ones sketched in Margon's plan.
