This for one reason retains the lip at the top to seat the fork bearing. Same with forks, taken out of middle. Good look. Think Knowledge did a post on this at some point.
Interesting method. As I have a TV200 frame to 'unreduce' it is something I would consider, though I have a complete donor frame so could substitute the whole fork tube. I suppose that if fine threaded taps & dies were available a fully threaded tube could be screwed inside. I'd trust that method if correctly Loctited in place as (I doubt you could ever get them apart!) if they came loose, you'd soon notice via the forks tightening up. Like a steering damper with no steering
The trouble is with either method is maintaining the "provenance" IMHO because 'matching' of the welds to the size & high quality of Innocenti.
As a consequence, to get fully back to subject

my belief is that Innocenti Li III to Innocenti DL is 25 mm so the 28 mm mentioned would make sense.
