Here is your answer. These modifications took a Agile Harm One 12 and turned it into a '60s-style beauty -- sort of a 'resto-mod' guitar:
Mini-humbucker pickups replaced with single-coil Vintage Vibe Guitars set with 'Ricky'-like tone, stainless steel housings with exposed pole pieces.
One set of tuning machines left stock; the other replaced with pearloid mini-buttons; making finding the strings much easier When you are tuning!
Trapeze bridge holds the fundamental strings closer to the body for better bass.
Octave strings still use the stock tailpiece.
Chrome pickguard replaced with a vintage-proper white one.
Knobs replaced with ivory Q-Knobs.
The guitar is well balanced, no neck-heavy drift like many electric 12s. It has a wider neck than a lot of electric 12s, making it easier to access string pairs.
