Argentina
Argentina's "Jetcorch" appears to be the design of the Geneva, Switzerland inventors
Serge Mourreau and Marcel Gonnet . When their gas powered ejector was ready for
use, the cover was removed and inserted into the top to be use as a lever to push the
"Sparklets" type cartridge down and engage it with the top of the needle.
The box is labeled "Industria Argentina" and "Es un Producto Promover, S. A." and
"Jetcorch" is indicated to be a registered trademark.
