The stamp in the posted photo sure looks like Ascorti plain and simple. Not all stamps are well imprinted,
but this one is clear enough. I have a little Greek PTM Amadeus that only says adeus, and the Made in Greece
is so small and rough, you aren't quite sure it says Greece, but I know it from its picture at the online retailer.
But this one looks like a pretty clear Ascorti stamp.
