I noticed in the FAQ section that it is called out for TRW Power Steering Pumps to be BLACK & Ford/Thompson Pumps Teal blue.
My '67 pump still has a date-correct tag on it:
HBA-BF
I F
6K17B
(actual build date 11/2/66, other power steering parts dated within less than a week of October 17th)
Pump is now painted BLACK and there are NO signs of teal paint underneath. So, if it has been repainted, it must have been stripped maybe? I may have done this during an engine rebuild, I was known to fully strip things like this of paint before repainting.
