Need an autoflush water valve assembly for a 1978

[Clwsunny15]

I have a 1978 hi lo 25'model # 2476. I need to replace the autoflush water valve assembly. Does anyone know what kind of toilet is in it? It isn't plastic and has the single foot pedal. I have found parts for different series. Thank you for your input

Usually you will find an ID tag on the backside of the bowl near the floor. This is where your phone camera comes in handy.
