Gothic Revival Altar Reredo

This is my restoration project --- a 17th - 18th century gothic syle reredo (altar back)... When I found it it was covered in layers (and layers) of cruddy white paint... Three months to get that off... Now looking for a source test to help me restore it's original brilliant colors, golds, read and greens, mostly... Small gargoyles at the top... If I had to guess, I think it originally came from Belgium.
