Seems it is mistake in the date and, as result, another steamer <i>Blochem</i> depicted on this photo. Like it is Blochem, which was built in 1921-1922 years, which after <a href="//commons.wikimedia.org/wiki/Second_world_war" class="mw-redirect" title="Second world war">Second world war</a> was renamed <i>General Chernyahovsky</i> and joined the Soviet Union merchant fleet, <a href="//commons.wikimedia.org/w/index.php?title=Black_Sea_Shipping_Company&amp;action=edit&amp;redlink=1" class="new" title="Black Sea Shipping Company (page does not exist)">Black Sea Shipping Company</a> fleet, in 1946.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1">[1]</a></sup> Finally we can say that two steamers <i>Blochem</i> were in Germany fleet: one was used during <a href="//commons.wikimedia.org/wiki/First_World_War" class="mw-redirect" title="First World War">First World War</a> and seized by French; another one was used during <a href="//commons.wikimedia.org/wiki/Second_world_war" class="mw-redirect" title="Second world war">Second world war</a>. This ship is the second one.
