In the '60s the Galanti company manifactured in Italy combo organs for VOX, as well as their own products under the GEM brand.
The "P" model (which will later get a different stand and will be renamed "Jumbo") is obviously a VOX Jaguar clone.
Before this one I have owned both a Jumbo and a Vox Jaguar, and for what I remember (and according to my old recordings), I find very little difference in sound.
