Without an image I can't tell you much, but most of these secretary desks are " Colonial Revival", or "Federal Revival" examples after the fact they copy design motifs of American Colonial or American Federal pieces.These were made in huge numbers in furniture factories that centered around Grand Rapids Michigan. Values for them today depend on conditionm and quality of construction. Comparable examples to yours in " as is" condition they often sell for about $500.00 .
