I checked again and the only Heritage Furniture is Drexel Heritage !! But Drexel bought several other companies so this may have been one of them !! Not sure when they started using the Heritage name with theirs !! 2138 is probably the style number And the retailer where your family bought the sofa was Knorr Furniture, Midland Texas unless they bought it used !! Like I said before,, the sofa is made well !! Quality furniture usually sells well !! Check on ebay for some prices on their sofa`s !!
