I've received a lot of questions about the new coil:

https://www.dropbox.com/s/2s04hl1zhs4qfhd/25mh_coil.jpg

The form is a pool chemical container from about 20 years past.
Resorting to a more sensible measurement standard I conclude the following:

Total turns counts 325

Coil length 375 mm
This indicates a wire size of AWG 17 which is 1.15 mm diameter (375 mm / 325 turns = 1.1538 mm per turn) 

Coil diameter 350 mm
This calculates to approximately 24 mH which is close to the 25 mH I initially measured which I later revised to 26.1 mH.
However I've made so many calculation errors recently this also may change :)
