Help identifying a pickup

[CarlR]

Hi, newbie here. I'm needing help in identifying a bridge pickup from a '72 Strat I bought at an estate sale.




I think it's a hot rails, but I've got nothing to go on. The two tone pots in the Strat are dated for 1967, and the volume is dated 1985. The people running the estate sale tried to find out a little more about the history of the guitar, but couldn't find out anything more. I've checked the resistance, and it's 6k on each coil.

Thanks for your help.

Yeah, guess you are right.... old style Hot Rails in double cream???
Seriously rusted blades by the way.
