Well youve answered another question about a differential. Looks similar to a surplus one Ive looked at to use for a sidewalk battery powered car for grandkids. Lets see a brake band on a drum. Somewhat like Henry Ford used on the Model Ts. So Im guessing the brakes and drive belt controls are interlinked to the lever. Hum another item Ford copied in his Model T. His level was interlinked for Drive, Neutral and what is sometimes called a Hill Holder Brake. From what Ive seen in the video of other Benz models it works similar. Ok in some of the pictures of other replicas people have built of this Benz vehicles Ive noticed a different size rear sprocket on some of them. Must have been hill climbing gearing option they copied. Just kiding. Also been wondering about the steering controls. I look forward to seeing how you replicate it.
