Well, regardless of what it _looks_ like, if it works, it works. He mentions that the HV compound was applied by hand, and it shows - but there's nothing in the functional specifications that say that the HV compound has to look good too. As long as the coil is well made, and wound properly, the only reason the potting compound is there is to keep everything nice and together, and prevent possible arcing. Something tells me that it's not easy painting a good, even coat on a doughnut shaped coil. Also, the lack of a core is not that big a deal, and makes sense too. If these are homemade, it's going to be hella hard to make an identical (or compatible) iron core and mounting assembly, but if you're replacing a fried flyback, it shouldn't be that big a deal to dismantle the old one and replace the coil on it. It's pretty rare that the core of a flyback should fail...
So, I think it's great that these parts are available, especially seeming as though a flyback is one of the big "make it or break it" parts for many televisions - hard to find and easy to fail. This part is probably just as good, if not better than the original part - I mean, he used actual HV putty, many old flybacks were coated in wax! Also, there's the other advantage as this is a new part, it hasn't been sitting, buzzing away in the back of a television, running at some off-spec input voltage, crammed in there with a bunch of hot tubes and failing capacitors, slowly breaking down the insulation in the windings.
