Sorry, that will be difficult. Your best bet might be to learn how to repair it yourself. Viscount Service is the "official" Baldwin organ repairer, although every town usually has someone who works on organs.http://www.mitatechs.com/suppliers.htm#Viscount_America_2
You might ask around town for a technician. Be prepared to pay several hundred dollars. (sorry!)
Oh, is this what it looks like inside?
