Bottom Flat Grate for Rayburn No1 Old Pattern. This is a Rayburn original part for No 203a. We only have one in stock when it's gone it's gone. Our supplier has now decided to discontinue production of cast parts for the Rayburn No 1, 2 and 3. Being first produced in the 1950's requirements have dropped and it is no longer economical to produce spares. We only have one of these left in stock and when it is sold we will also now longer be able to supply them.
