If you look closely at the back axle it would appear that this is a driven axle bike that has had the side car fitted continental side?
I think I can also just make out the engagement lever on near side.

Could possibly be a Steib sidecar - headlamp and tail lamp on the bike are clearly continental. Possibly an early machine as the front mudguard retains the number plate fixings.
