Gold Crown IVs can also have bronze pocket castings. The ones in the tournament room at Hard Times Billiards in Sacramento were like that last time I played there years ago. Also, I bought a used GCIV for home and it came with badly pitted bronze pocket castings (so I had all the castings, feet, etc. powder coated to the color I wanted for a very reasonable price).
Here's an example of a GCIV with bronze pocket castings for sale:
How bad was it? Three out of the four rails I checked were dead (as in solidified) and all metal corroded (as in submerged in Katrina). "But, completely rebuilt after the hurricane." Asking price: $3000. And the beat goes on . . .
