[Seaplanes]

My information is from the original Flugzeugübergabescheine (Aircraft delivery forms) available at the Bundesarchiv-Militärarchiv in Freiburg in the RL 3 record series. These forms give the name of factory, W.Nr., normally also registration in the D- range, date of delivery etc. The reason for using W.Nr. blocks out of secuence with the Blohm & Voss production of its own designs is not known to me, but it seems that this was common practice in order to avoid duplications of W.Nr. for a specific aircraft type. The W 34 was produced by a number of licenced factories apart from Junkers itself and it is easy to understand that the risk of W.Nr. duplications was high.
