Baile 48 bass compact piano accordion (sold). Made in China this instrument has 2 voices and 30 treble keys, which means you can get down to the lower G, which is very satisfying (especially if you are used to playing on a two octave instrument). This would be ideal for a learner as it only weighs 6kg, which for a piano accordion is quite light.
(Sold) Hohner Student II piano accordion in RED. Made in Germany. This (was) in unused condition with no wear at all and with its original matching shoulder straps. This little accordion has 26 keys and twelve basses, which in practice means bass fundamental and chords in Bb,F,C,G,D,A. Major chords are normal for the Student II, but I removed the major third note for each chord, so they work for major and minor tunes. Please see the video for further explanation and demonstration, This is a great little instrument, perfect for busking or learning.
