There is a simple explanation. I purchased this concertina from Kurt via his posting approximately 9 months ago.
It never occurred to me that someone would think the new for sale ad was a scam.
I posted the same photo he posted originally, and reused much of his wording since it accurately described the instrument. When I purchased it, I appreciated his inclusion of the link to the maker's blog with photos, so I also included that link.
I've not taken the time to learn to play it, and, (like Kurt), decided to sell it.
I will be happy to send current photos if someone is interested in purchasing the instrument.
