FWIW, the USRA 0-6-0, similar to the IC 0-6-0, has been produced twice by MTH (in both RailKing and Premier versions; the Premier is a better model), and by Weaver in a brass version.
The brass is always a better choice for modification. They appear on eBay. I have one; good runners.
There are several brass Weavers on eBay right now in the $300 - $400 range.
