Beautiful shot.I have the Grumman SRM wing and horizontal stab station diagrams that show the increased span of both, but what they don't have is the chord of the stab, and the cross section of the wing showing the 'cuffed' leading edge and where it starts to curl down.
On this photo, it appears that the wing cross section at the nacelle is a 'standard' airfoil, but that the 'cuff' gradually increases towards the extended tip.

According to this page all versions of the Albatross had the same wing profile: NACA 23017 at wing root up to the wing tip.It looks like the leading edge droop (cuff) starts at the nacelle, and becomes more pronounced as it moves outboard.

That guy is collecting airfoil data - maybe he also can help out with the tail airfoils of horizontal and vertical stabilizer.
NACA 23017: camber position 15%, thickness 17%
On this page you can create the point clouds for the profiles. With the sketches posted here you have the corresponding wing depth at each position which is equal to the profile chord length. The percentages are calculated along the chord length.
The prominently visible droop on the wingtip has this reason:
The angle of attack of the wing profile at the wing root is generally designed to be about +1.5 to 3 deg (nose up relative to fuselage main axis, exact values depending on profile type).
