Would you please take multiple pictures out of the box so we
can see the winding technique and how things are connected!
It appears the secondary is center tapped. Please - out of the bos!

Gary - very interesting!
I would urge you to also post notice of your work on QRZ.com. There is
active discussion of EFHW 49:1 technology in the "Antennas, Feedlines,
Towers & Rotors" forum, with significant contributions by retired EE
professor Mike Mladejovsky, WA7ARK.

* This should provide a summary of posts from WA7ARK:
Have you yet had opportunity to evaluate FT-240-52 mix cores? It's my
understanding a triple stack of 52 cores offers better performance (versus
43 mix) for higher power HF applications - reference this 2019 YouTube
video from Steve Ellington:
It would be very interesting to specifically compare FT-240-43 versus 52
mix cores for HF use with EFHW transformers.
