Thanks everyone.
When taking it apart I was actually a little surprised about much it looked like stuff that is mass produced today, just without particle board, MDF and vinyl veneer. They just used different "cheap" materials than what is available today. The top was made from pine with surprisingly thin (for the day) veneer for example. The wood that divided the drawers from the inner cabinet was sort of like a thick veneer. Today they would use something like Masonite for that. I think that this was definitely made in batches with different steps that were obviously made using machines. I could definitely believe that different people made different parts and then that different people might have done different parts of the assembly.
