A couple of good photos of cartridge-starts on B-57's:

The RR Griffon used in the later Spitfires started with a Coffman cartridge starter. I found the sound file for it in one sound set and re-used it in my Spit XIV and XIXs. I also use it in a few round engine sound sets as well.
 
Tom....did you have to clean those cartriges? Where is that sound file for the Griffon? Are you sure they used that?
 
According to the RAF Pilot's Notes and other sources I found, the Griffon engines in the Spitfire did. I believe the Merlins used a different type starter. But the Pilot's Notes is what I've got on hand. I redid the sound package to use the Coffman sound instead of whatever starter sound that came with them.

Not sure if it was correct or not, but I also used it in the P&W Hornet sound pack that I use for the Gee Bee R-6H. I just like the bang, then the engine starting up.
 
Pistons aren't the only things started by those things. The Pratt & Whitney J-57-P-59W's mounted on the old KC-135A's had what amounted to an Estes rocket engine - an Estes engine that was 6" long and 8" wide! They burned in about 5 seconds and in that time the pilots had to do all the lever and switch flipping they normally did in 15-20 seconds. Eng's 1 and 4 were started that way, then those were run up and the inboards were started on bleed air. Less than one minute from butts in the seats to taxi-ready ain't nuthin' to sneeze at!

The only bad part was cleaning the cartridge receivers afterwards!

Goodness, lololol...

Rocket starters..

Amazing what we learn here.
