It is probably not exactly the same product. When KR and Brunswick went their separate ways, Brunswick renamed all their products and probably used a different supplier. But Factory Crown compound replaces Royal Compound to do the same things. So I wouldn't buy the new one to replace the old one. The old one replaced Rough Buff also to do the same general thing.
(FYI the bottle says 2500 grit, but it is a very aggressive compound and is generally used to take balls from a sanded 500 grit base into the 4000 grit range. When applied over 1000 or 1500 grit base, it will usually result in an almost polished appearance.)
