Fridge/Freezer, bought UK '67. No visible ID. Compressor 'dead'. Tech is prepared to repair if cubic capacity known. Repair notes (1979) identify model as RTF43 or RJF43. Two white stencils on top of compressor below fridge floor. One shows "SEP30 1965". Other is a 'roundel' with lettering, but can't read around corners! Would this be Part Number? Plate on compressor says T69, but is that Tester ID or capacity (cc)? HELP PLEASE, as is old friend?
