extremely poor focus

[Kiwick]

I've just found a 1968 "WEST" (italian-made) 20" B/W tube set on the curbside, it just needed a new heater ballast resistor and a 1B3GT HV rectifier, it works now, but it has a couple of issues...

First of all, the focus is really poor, and there are no adjustments for it, bad CRT?

Then, the vertical deflection works fine but sometimes collapses to a bright horizontal line while changing VHF channels, is this normal?

i'll post some pics ASAP!
