Identifying boxed minfig accessories capes etc

I have been sorting through my monifigs. I usually bag them as soon as I open sets but I have a couple of accessory boxes that I can't identify. I assume they are capes of some kind but a Google search of the part codes returns nothing. Does anyone know of a look up resource for these? The numbers concerned are 6117459 and 6117770 but I'd be interested in a site where I can look these up in future
