Here are 2 Hemi No 9 script pieces from my collection.LH One is a dripped, script type with underlined "O" and the RH is a dripped script type without the underlined "O".This leads me to believe that Hemingray DID take an early production SB mould(specifically an EIN [230],added the 5/2/1893 date to rear skirt and a dripped baseplate to it and started production of what would become the EIN [250] using the EIN [230] mould. Only a little later did they make the correct [250] mould and continue production. That's my speculation from observation of the pieces in my collection and their similarities.
