I get the impression that back then there were some Frankenstein regulators that might have originated right at the factory. It seems that sometimes they just put together stuff with what they had on hand.
The blistering is odd, but the rest of the paint job looks very much like the factory finish. Not just the color, but the texture looks to me just like the other can.
Back then color matching was an art... not the developed science they have now a days.
Like Bryan said, if the can has no tabs and the paint is missing from the edge of the hole, it may be an original single stage can that was modified.
If the can has tabs or the paint on the edge of the can is intact, I am guessing that this is a factory Frankenstein. A prototype or one of a kind that was put together for some reason that we may never find out.
