"Logan String Melody II. Made in Italy and and also distributed by Hohner internationally so some are labelled Hohner or Logan String Melody.
This is a Logan branded model.

All of the keys work, although a few are slightly quieter than others, some feel a bit slacker and some feel a bit tighter than others. At the treble end there is a faint sound like a few keys are pressed down, however you cannot hear this when you begin to play.
The keyboard is split in the middle, with the lower half called Bass and the upper called Treble. There are three drawbar volume sliders for each of the three sounds in the Bass region. These are the red sliders in the photographs.

There are also three sliders for the three sounds tin the Treble region these are the blue sliders in the photographs.
The two left red sliders are a bit stiff and do stick sometimes. One of the red covers has come off, as can be seen from the photographs. The blue ones move fine. On the metal slider cover the are two slight dints.
It also has 5 preset sounds. These have push button switches, all work fine.

In back there is a single 1/4 inch audio output and a volume control pedal input.
It comes with original power supply. Some of these I have seen for sale in the past have been sold without the power cable and have been untested or have been butchered to have a newer style plug fitted. This is all original.
It comes in its own built in wooden case, the lid fully removes off. For condition of case please see pictures, it could do with recovering."
