Advice please! Antique newbie looking for info on estate sale find.

I recently purchased an 'expand-o-matic desk at an estate sale. The plate says that it was manufactured by the Saginaw Furniture shops, Inc. The front legs pull forward about eight feet to unroll a tambor top working surface. I'm not sure how to research something like this. Can anyone tell me anything about the manufacturer or aproximate vintage of this desk/table? I have been able to find out only that the manufacturer existed around 1928 in Saginaw, Michigan.

Write to the Saginaw chamber of commerce or historical society and ask them.
