It looks like you have full deflection but poor focus. That probably isn't hard to fix. There's probably fixed resistors on both sides of the pot...just need to move a resistor from the side the wiper is touching to the side the wiper isn't touching to get more range.

Actually the focus is perfect it’s the camera I used I wish I could get a nice picture to post. And I could not move any resistors at the pot because the voltage coming off the last resistor from the network feeds vertical so I had to use resistors at the tube base had to drop focus voltage from around 350v to around 125v I originally tried the resistors at the pot and lost full deflection.

Tried to get the picture better but cell phones not good for clear pics the picture is bright and focus is clear despite what the picture shows. Now a pilot 37 with a b&w picture no more hoping for an unobtainable 3kp4.
