Yes we already made a metal shim for the 40mm FD mounts that are more easy to find. ITs mounted up and in the pictures above.
Watt meter installed also

Here are some links to parts I think needed for a good FD for brompton.

Also need to tweak the cage for good shifting, two screws for litepro mount around the tube ( Stainless Flat Head Countersunk Hexagon Socket M4x8mm and might need to be filed down), blue loctite in beginning then red might be needed
