What model is this 1950's Westinghouse Electric Wall Oven/ Replacement Element (QLD, Australia)

Hi. I have a much-loved 1950's Westinghouse Electric Wall Oven with separate grill. When cooking on Christmas Day the element started to heat up - then nothing. The panel lights still come on so I suspect the problem is as simple as the element. Today when I phoned a couple of electricians they both said they needed the model number to be able to check if they can still source replacement element, however as the oven was in our house when bought it in 1999 I have no idea what model it...
