Hi,
During WW I the Dutch captured a Hansa Brandenburg W12 in April 1918 (which went into Dutch service as W1) and this seems to have been as good as immediately the model for 35 Van Berkel WA planes, which were produced untill Juli 1920 by this company at Rotterdam.
Was wondering if anyone has a picture of it ? And if it was an exact copy or not ?
Thanks and best from Johan
