The manufacturer field on our records points to Renold, but the description plainly calls out RK of Japan as the actual maker, so that's what we're going with. 420 chain in this width shows up as a final drive or primary chain option depending on the machine it's speced for, and the catalog doesn't tie this particular listing to a specific model.
If you're replacing a chain, check your sprocket count and chain length needs against this 120-link size before ordering, and give us a call if you're not sure this is the right pitch and width for what you're working on.
