Teddy Ruxpin adaptive switch toy (non-working)

Made by Enabling Devices

•  Has three large switches on the base, three sets of cassettes and Teddy Ruxpin books; owners manual
•  It does NOT work.  It is missing the battery box necessary to put batteries in it.  This is a discontinued product and we have not been able to find a battery box to fit.   Hoping that there is a parent or therapist that might be able to get this working!
