In Netherlands Philately 43-3 I wrote about a cover recovered from the mail boat s.s. Berlin, which crashed on the North Pier at Hoek of Holland during a heavy storm on February 21, 1907. Willem Pasterkamp, one of our members and active as a trader of postal historic material, provided interesting additional information. Willem notes that the marker “BESCHADIGD DOOR RAMP HARWICH BOOT ” consisted of loose characters.
At some point in time, the first characters must have fallen from the marker, and was put back upside down. Figure 1 shows two impressions of this marker on one cover example. Another type of marker exists, with a wide space between the first and second line (see Figure 2). This cover was part of the disaster mail collection of Willem Baron Six van Oterleek, and is listed in Auction Catalog 595 of van Dieten (May 27, 2004).
