The Pre-production and the ESB flame throwers were not the same.
According to LFL rumor/legend, the Pre-production suit's flame thrower was FUNCTIONAL. But stories can grow pretty wild in the past 20 years.
It does appear to have the nik-nak on the end of the flamethrower to ignite any fuel fired out the main tube...who knows??
The ESB greeblies don't resemble the Vader chestbox pieces, but I was considering using some on my costume.
I never got around to adding those pieces. Maybe someday.
