Yes, I have seen that design nowhere, but just on ebay as their models, the interesting design of having bridge very forward and funnels etc. more behind. I am courious which name they will get, as they will be chartered from C. P. Offen to MSC, it seems.
Regarding the Sietas-ships, I didn't find anything on ebay, but they are as well not so spectacular vessels, that lot of models would be around.
