Boyen pianos?

[Barbosa-piano]

 I had a Boyen upright piano from Germany on my grandmother's house, and it was very good, had a unique sound, but was way too old, and nobody cared for it, it stayed for years in a restaurant saloon and in an dirty shed before that. It has many keys out of tune, but it was fine before that. It is very hard to find.
I was just wondering if any of you ever heard of it or played on one with better conditions than mine. I would be thankful for replies... Thank you!

I realize it would be expensive, but a good technician might be able to get it back into good shape.

Perhaps if it means a lot to you, you might want to consider that.
