Dating old P bass pickups

Hi Guys

Not sure if anyone can help with this but I'd very much like to try and work out what year my P bass pickups are from.  Both pickups are stamped 6466 on the base and although the last two digits are a little smudged it's fairly clear that they are 66.

I was told that the early P Bass pickups in the 70s had a 4 digit code but this stopped in '73/'74.  Thereafter the code became a 6 digit. All the later 70s P Bass pickups I've seen with a stamped code have 6 digits and that inlcudes my own '76 and '78 P basses.

Not sure if it helps but they are 10.3 ohms.

The wires have been replaced as can be seen in the photos. Anyway, here's some images and thanks in advance for any advice! 

I got one helpful response from someone on Basschat who posted a photo of his P bass pickup with the same 4 digit code as mine, and the pickups look identical, and his bass is a 1970.  So I wonder if the last 2 digits are the year?
