The screen is way too large. A classic screen should display 7.11" wide by 4.7" high (I assume being outside the US, 18.06 x 12.06 cm would be easier). The screen won't even project where you are seeing that distortion at the bottom. If it persists, one of the deflection magnet rings on the back of the CRT yoke might need some adjustment. I'd get the height and width adjusted first, though.
