What is the value of a miniature mouth organ shaped like a boomerang in original case about 2 inches long?

Answer 1

There have been a couple of these small boomerang shaped harmonicas come up on trademe.co.nz in the last few years and have sold for about $75-$100. They were made by Seydel in Germany for the Australian market between 1920 and 1970, and marketed by J. Albert and Sons throughout Australia. They also came in larger sizes. In 2004 Seydel reissued the larger boomerang model. One thousand of these reissued harmonicas were made. The original stamps were used for the covers.
