OOOY VEY!! I don't know where to even begin on this. Even a seasoned techie, if he knew beforehand that all the vid IFs had been tweaked with, would have thrown up his hands and sed "No Way!"

Back in the day there was a shop that had a proficiency test for new hires. The boss would take a set and deliberately throw the vid IFs off. The applicant was expected to re-align it using the full suite of equipment (sweep genny, scope etc.)

The fact that you've got a watchable picture on the set is nothing short of a miracle and testament to your Granddad's indomitable spirit and admonition to "dig in and do it." It's virtually fulfillment the Sea Bees' motto:

The difficult we do immediately
The impossible takes a little longer.

My hat's off to you Sir. I would never have even attempted it.

The usual symptoms of misalignment are loss of fine detail in the pic, smearing-out and ringing of the vid signal. The best advice at this point would be to not try to "improve" upon what you've got.
