The following is a list of accordion models/makers thought to originate in China.
This is not an attempt to qualify the good or bad - just inform of the country of manufacture.
How you use the info. will be down to your own interpretation and research - and possibly the input from the members on the board.
The list has been gathered from previous posts by the members; often 'from memory' so there is room for error.
I'll edit it to include info from later following posts or from the discussion here: viewtopic.php?f=3&t=1526&hilit=pearl+river
And a big THANKS to JimD who provided much of the info. Much appreciated JIm.
