Hutch/Sideboard

Hutch/Sideboard acquired by my father over 50 years ago at an auction.  The family home is to be sold soon and we would like to know an estimated value.  He was told it was flemish. But we are not sure.  I found a "1313" on the side of one of the drawers.  Also the underside of each drawer has a Lelt (Not Left, it says Lelt with an "L")  and Right.  I also think what I may be a "D" on the inside back of one of the drawers.  He was told at the time is over a few hundred years old.  But no other information is know.
