Looks like you have been doing some work. In response to a request for feedback I offer the following
1- As mentioned the PS tag, the upper mounting stud and retaining nut would have been on the pump when painted (this often leaves a shadow and bare metal under the tag. Have seen them painted with the cap installed and without. End of the pipe where the return line goes would not have been painted originally
An original example
2- Agree that the AC pump was painted as a unit after assembly - some original examples
3- Do each of your exhaust lacks have at least one ear (each bolt) bent over and in contact with the bolt? Often owners don't finish with this detail
4- Not required but you could have provided a little engine paint overspray (a little or allot) on the carb spacer
An original example (car had 1200 miles)
