That would be the one I'm referring to. Although this is the second one I have seen in the last few months (the first was on eBay-Italy). I noticed the crooked switch, but wasn't sure if it was just loose or something. I actually asked the seller, and he told me that his parents bought the machine in the 1970s and he couldn't imagine that they would have modified it.
I didn't know if there was some period where Pavoni found some old first gen groups and started placing them on two-switch bases. I have always been curious what the "rare" and sought after Pavoni machines are, and i thought perhaps a first gen with double switch would fit the bill!
