Cordovox Model CXP Power PackCordovox
First off, I'm going to start by saying that this unit is untested. Unfortunately, we don't currently have an accordion or an appropriate speaker rig to test this. It does power up when turned on. There are some chips and scratches and the metal casing and the front grill has some bends and small holes. This is a Cordovox Model CXP Power Pack. It was likely manufactured in the late 1960's. An internet search on this turned up zero. What does one do when the intrawebz don't have no answer?? Sell it as is, that's what. Someone more knowledgeable than I am about esoteric, extinct, obscure, non-Google-able vintage accordion equipment will surely know what it is.
