I believe I have some of these crosses. I have a rooster and a hen with dark barring and some gold/red leakage. The body type of the hen is exactly like my two ISA brown hens which are RIR/RIW sex-links here in Europe. She looks like a carbon copy except she's barred where they are pale red with white tails.
Here is a picture of my Roo.
He's bigger now, he was only 4 months old in that picture I think. He has perfect gold hackles and saddle now, not just messy leakage. More like a barred Red Birchen. He's a nice guy, chest butts my foot every now and then, but overall a gentleman, and sweet to his girls. He even lets my BO rooster get a little action if he's not close enough to push him off the hens.
The hen is a great layer of medium brown speckled eggs, identical to one of my ISA brown hen's eggs. I have a pure BR that lays "skin color" eggs that are completely solid and look like they're painted with latex, so the eggs are definitely more like the RIR. They say the egg color comes from the rooster.
