In April 2016 Ebay seller snowman100 from Utah in the USA was trying to sell this sample Somalia plate.
It is probably from the early 1980s and it is a failed test design. There are at least five of these with the same number in collections. Somalia never used anything like this. It has come straight from the German manufacturer’s scrap bin.
Even if it looks like it could be genuine, always check that a plate is close to that particular country’s genuine plates. There are several websites like Francoplaque and Plateshack that have pictures of genuine plates.
