Update --
I installed the gen free-sprung balance & auto-wind parts. So, as far as I can tell, there is nothing left that would appear out of place on a standard 4130.
Also, to address potential 'Is that real?' inquiries, I installed a display caseback (last pic) so the inquisitor can look & decide for him/herself.
As best I can tell, the movement is now a 1:1 clone of the original. So, unless I missed something, the mechanical transformation is now complete.
However, there remains 1 important piece of The freddy333 Daytona pie. Coming soon..................
