I want to add, since the topic isn't actually being discussed, that serial numbers are only used recently by Butterfly, perhaps to prevent copies coming out of China. The first generation of Butterfly has only the metal logo. The oldest has the word Butterfly in nice calligraphy (black letter?) or no writting on the playing surface at all. Then block letter(?) Butterfly, no fancy writtings, being the more recent. Then the serial numbers next. Then the silver logo and serial numbers. I have serveral old Butterfly I am very proud of and they still play great.
Now if we talk about Butterfly before the late 70s they don't even have the metal logo, I think. It should say something like Tamasu co only. That's my guess from seeing a few of the older ones.
