Saba 50: Freezer Model?

[Wishbone Too]

I purchased a used Saba 50 with 3 refrigeration units, (cockpit, salon draws, salon next to stairs) and NO freezer. Looking to get the model number of the Isotherm freezer normally installed on the SABA, (probably same as Elba and Saona I suspect)? And if anybody needs a replacement fridge in the Med. Let me know I may have one for you!
