Dual seat TF-102 picture.

Here is a great one from Bert Buss. Not many pictures of the dual seat TF-102;

 This what Bert said.

This was the engine start package for the Deuce. The Joy MC-1M hi-pac and a MD-3. In the alert barn we had motor driven MC-1As for electricity. The MC-1M was essentially a stop-gap starter until the MC-11s came onboard. While the -1M could only give one shot to start without recharging, I think they could drag two attempts out of the -11s, which had more receiver capacity. That 3500psi went pretty quick in either case.
