Are the wing ballast tanks of the 27B, 28, and 29, fabricated as
complete assemblies separate from the wing skins, or do the wing skins
form the tanks walls?

Comment from anyone that has seen the wings being built, or has seen
one opened after build, appreciated.

thanks

They are comprised of the upper and lower wing skins, the spar, end
cap assemblies, and baffles.
When all glued together, it is a wing with internal tank.
