David,
I looked in 2 publications:
The Journal of the Television Society published this:
The Black Book gave this waveform:
So, the J of the TVS mentioned at least 10 suppressed video lines per frame, resulting in 385 actives lines or less.
The BB specifies a video suppression period of 14 video lines per frame, resulting in 377 active lines.
= the numbers you already mentioned.
