Hello MMD,  I have recently added a listing for a 26-note
Hofbauer organ onto the secondhand page of my website at

http://www.grindorgans.com/ 
http://www.grindorgans.com/used.html 

So if anyone is interested they can go and check that out.  On
the other hand I have ongoing inquiries for used Raffin organs.
If you are pondering of selling yours, please do get in touch!

Musically,

Stay safe!
