TSR brake adapters, genunine

This kit popped up on ebay while I was for 256 upgrades, after putting a bid on it I'm worried it's not genuine and it's just some brackets someone has made and is badging as TSR to get them to sell. Could anyone confirm if these do look like TSR adapters or some home brew stuff?
