And build by CMASA in Marina di Pisa in Italy. The D-6 till D23 where licenced buildt under Donier Metalbauten Gesellshaft and produced by Aviolanda Aircraft Construction Company. A slight hull modification was made for the Dutch flyingboats that was incorparated for the other Wals build everywhere. The rest of the Dutch Wals where equiped with the more powerful Lorraine Dietrich engines with 450hp. Later series where produced exclusively under licence by Aviolanda in the Papendrecht factory near Rotterdam. The Wal is equiped with the 'sponsons'the short wingstubs witch give the Wal a good seawortyness. Also there was the possibility to mount a pair of wooden wheels on the sponsons to bring her out of the water iff needed. The Wal was capabel too take off safe, on one engine!
