I have a question, I am driving a 1969 model, there are two levers on each side of the handbrake. what are they for?

Usually, the two levers on each side of the handbrake were used for heating and defrosting the vehicle. It was before the conventional knobs on the dash were placed for easier use.

Hey taking the time to answer!!! :) really was curious as a cat!! curiosity quenched. thanks a lot colin!

Okay- so which one is which?? How do they work? Cheers

The levers basicly opened a flapper between the engine compartment under the back seat on each side is the flapper.

the two knobs were used for heating and defrosting the vehicle

They are both to heat: the lever on the left makes the air from the engine (heated) enter in the car, the other one conveis the heated air in the anterior part of the inside of the car

Burn84 is it okay tell me how the backrest of the drivers seat is adjusted, is the adjustment by a turning a knob to change the angle of the backrest? i have looked online for an answer but have been unable. I am making a house chair but needs the info to finish the chair, Thanks.
