Anyone know model of this 1950's Westinghouse Wall Oven?

Our much loved vintage 1950's Westinghouse Electric Wall Oven (with separate grill) has stopped heating. The panel lights come on when turn it on but it does not heat up which leads me to believe it needs element replaced. I have made contact with a couple of electricians who have both said I need to give them the model number for them to be able to tell me whether or not a new element can be sourced. Does anyone recognise our oven and know the model? It's with hope someone mid or pre-renovation may have or have had the same type. Also, does anyone know any oven repairers who service the Ipswich or Brisbane West suburbs? Many thanks.

Model number could be on the back if you slide it out of the cabinetry. But 1950’s... probably time to cut your losses and upgrade.
