Antique Desk 1800's New England

I am trying to establish the value of a desk that was recently destroyed in a fire at my daughter's house.  The photographs are of a nearly identical desk currently listed on ebay.  The desk in question was the same except the drawer pedestal and storage cabinet were located on the left hand side of the sitting portion and the drawer pulls were single piece carved wood instead of the two metal rings on each drawer.  The desk was in similar condition to the one shown and has been in regular use since we aquired it at a flea market in New Hampshire in 1971, for a long time in our house and more recently at our daughters house.  I am almost certain that our desk was also a Stephen Smith Desk Warehouse piece made in Boston and my recollection is that the manufacturers mark on the inside matched the Stephen Smith mark shown for other pieces on ebay.
