Bate's Suprize?

Can anybody confirm or deny the authenticity of this BATE'S headlight? An Egay purchase from early October. The guy said it was from a 1966 Servi-car and it was listed as "After Market Headlight". One picture listed did not show the back. I got it for next to nothing, got husltled for an extra $10 shipping after they guy invoiced me, and it took nearly a month and a freeking half to get here. But...Then I unpacked what I believe is an original Bate's headlight. Either way...happy with the bate's or bate's style light and looks great on the bike.

Update: Confirmed! The numbers match. This is in fact a BATES Headlight. It's just missing the BATES sticker. Not worth as much as I thought, but I still payed the right price fo'shua!
