Need help with wheel hub for a sprocket-Douglas wheel alloy

#1
I need some help... I'm kinda stumped :eek:ut:... does anyone know of a wheel hub available that would fit the wheel below and allow me to mount a sprocket? I want to use this wheel as a rear on my Trail Horse but cant find any hub out there that would fit this wheel and allow a sprocket be mounted to it..Any help would be appreciated!
