I think ThomBassmonkey is right. The name "Palmer" was not mentioned then, but I remember thinking "oh I've got a Palmer with a headstock like that". Two other names were mentioned, but I can't remember what they were.

iirc recently there was a thread by a guy asking the same question and his bass had the same headstock shape. I can't remember what the results were, maybe if you search you can find it
