Joel,
I have seen that moulding within the past month but, worse than your situation, MY brain has begun final dessication and is rapidly turning into "brain jerky"!!
You're right, it is a moulding that is available down here but I will have to do some digging to find the catalog that had it pictured.
Hopefully, another framer will help you out before I can locate my magnifying glasse and get that haze out of my head from all the drugs (pharmaceutical type, that is.) and find it for you.
