Although nominally a development of his earlier DFS Rhönsperber, Hans Jacobs' Sperber Senior was a completely new design intended to improve on the performance of its predecessor and to accommodate larger pilots.
[1][2] The Senior had a completely ply covered fuselage with a narrow ovoid cross section which was deep in the cockpit area but tapered progressively to the tail.
The cockpit was just ahead of the wing, covered by a multipart glazing which, attached to a small area of the upper forward fuselage, hinged to the right for access.
A tapered, round tipped and largely fabric covered horizontal tail was mounted on top of the fuselage, far enough forward to place the trailing edges of its elevators at the rudder hinge line.
[1] The Sperber Senior first flew in 1936 and took part in the Rhön German National championships of that year but its pilot, Ludwig Hofmann retired for personal reasons midway through.
