This is a set of left-and-right freezer hinges to replace the hinge parts of the Norcold DE441 refrigerator freezer door.  This particular fridge was installed on 90's-era boats, notably Bayliner brand cruisers. 

Manufacturer: Norcold

Model: DE441

Replacement for part number: unknown.

The original parts were built to replace the disintegrated hinges on a DE441 installed in a 1997 Bayliner 3258 Avanti.
