That's a Kauffmann starter, also used in a lot of aircraft up to the
F-4, at least. it was a pretty big shell (at least for an F-4) with a

production.

I think the USAF used them. The Marine F4J and F4S I worked on required compressed air to
start.
The Kauffman starter was an emergency use only
sort of thing, for when an aircraft was stranded
at a field which didn't have the appropriate
huffer to start it. There was a time when almost
every aircraft had specific starting gear,
different from any onther aircraft, driving the
logistics people near to distraction. Some were
huffers of various pressure and mass flow. Some
moved huge amounts of air at low pressure, others
moved small volumes at high pressure. Other
aircraft used electric starters of various
currents (pretty much all of those were ~30 V.)
All the F4 models use air start turbines, and
needed 28 V DC to operate the fuel valves and
ignition system.
