You own a pretty uncommon model, John. You might have to take the initiative to find other owners.
You could try searching- either through the registry search or the community search, not sure the best way (Donna D. would know).
When you find some, check their profiles to see if they've been logged in recently, and if so, send a PM or an e-mail.
As soon as I say it, no doubt one will chime in... Best wishes!
