I may have a different opinion on this, I don't think it's made from Scheid, Because the last letter of the Order of Alexander produced by the manufacturer Scheid takes on the typical shape of the number "8". But the last letter shown in this topic does not have such characteristics. But in terms of manufacturing time, I think it may have come from the First World War, but it was not made by Scheid but from other manufacturers, possibly Bulgaria’s own manufacturers.
