Really hard to say what the switch is for until you trace the wires out. The power antenna is a push/pull switch and would have 3 wires -- l from 6v in and 2 out to the antenna but it is possible someone has added something else.
The windshield washer in the photo is the standard all vacuum unit for 51-3 so no electric action on that one. To make the washer operate the wiper knob is turned opposite against a spring to the way that turns the wipers on and held for a few seconds. That moves the valve on the wiper motor to the position where the port on the motor driver side end gets vacuum which goes to the washer to pull the piston up for a charge of water. The knob is then released which stops the vacuum and lets air in so the spring in the washer piston can force it back down and expel the water charge. Once water starts squirting on the windshield the driver keeps turning the knob to start the wipers and clean the windshield.
All heads from 48-54 will fit on the various blocks and the various size number designations cast in the heads mean very little. As a matter of fact it was a Packard approved mod to swap heads in certain combinations for owners who wanted increased compression ratios. Your engine could have a head from the small 48-50 engine. The sender had the same ohm range and operation from 51-56 but the senders for 48-50 are a completely different type electrically and mechanically and may have larger threads. I don't remember or have one of those senders to look at. Ross is probably correct on the drilling out.
There is also vacuum in the choke housing that is pulling air thru the tube coming from the heated choke stove in the exhaust manifold. If the starter switch is OK and tube connecting the choke housing to the manifold is missing or out of position that might be making a noise.
The hose connections to the brake do make a difference although if they are reversed the brake will have no power assist so doubt that is the issue. 52 power brakes with the separate filter assy was generally one year only but it could be retrofitted to 51s so possibly a few of those are out there too. The unit has a sleeve valve to control vacuum to the power piston but in 53 onward they went to the poppet valve type which has the built in filter.
