Fin from a Halberstadt CL.IV belonging to Paul Strähle
This is the fin of a Halberstadt CL.IV. The prior owner, Ken Smith, obtained it from the gentlemen who acquired the very large Strähle collection of Halberstadts and Halberstadt parts, Ken Hyde. Paul Strähle, a pilot in Jasta 57, survived the war and operated a commercial air photography business thereafter using disarmed Halberstadts. Paint residue on the thin wood veneer of the front of the fin suggests that at some point the fin was painted silver.
Dr. Holger Steinle explains that the vertical pieces are correctly wrapped in lozenge fabric in a technique called marouflage by the French or tarnstoff by the Germans in which fabric is dipped into a hot glue and then tightly wrapped around structural parts to strengthen them.
Dr. Steinle of the Deutsches Technikmuseum Berlin, now MVT, is well known for his efforts in restoring the Strähle Halberstadts. The photo to the lower left is from his book on their restoration, Die Halberstadt CL.IV D-IBAO by Marian Krzyan and Holger Steinle, Verlag E.S.Mittler & Sohn GmbH, Herford und Bonn. On the shelf in the background can be seen two Halberstadt CL.IV fins as well as a rudder to the right.
The fin can also bee seen on this original, unrestored Halberstadt CL.IV on display at the Brussels Army Museum in Belgium.
Here are more photos of the Halberstadt fin, taken from below the fin looking up through it.
