I was curious if anyone had ever considered or mounted this Top Box to their Rocket III Touring. Very pricey (but stylish) considering you have to buy the lid of your choice, the back pad and the mount separately. It looks like a nice unit. See the related products at the bottom of link as well .
Pretty sure they are just re-purposed badges. Broken one off a R3T RHS hard case pannier and the big caps are probably Triumph car ones for a Stag, Herald, Spitfire etc
