Silver-plated Bi-Plane Desk Companion by F. Reichenberg, Germany.
The pilot and gunner seats are occupied by two glass silver plated screw top inkwells. The side of the fuselage features two hooks that are for holding a dip pen.
On the tip of the wing, next to the RAF Logo, it has the following inscribed:
"FRANZ REICHENBERG BERLIN D.R.P."
