Looks like a NGK Y-146R which crosses to a HKT PT-107 QGS Style, Bosch GPT-212 and Champion CH95, the picture below compares it to a Y-147T which is the correct GP for a non superglow 3B:
Yup, I used the Bosch 80018. They had the NGK part number in the system but no stock. Here's a pic comparing to the 10.5V y147t and the stock 6V Denso.
