As long as the scope still works, it should be fine. The biggest pain about using those old service grade scopes is the lack of calibration on the vertical attenuator and horizontal timebase. You can't be sure of actual amplitudes or frequencies with one of these things. A better grade scope will have vertical amplitude controls marked in V/division and horizontal sweeps in time/division so you can make actual MEASUREMENTS with the scope, not just see the waveform.
Yeah, inside the manual it has a section about TV testing. Wish it went into detail, but it's a start.

My brother says it works and is calibrated. We'll see.
