This is an old Dietz Union Driving Lamp. This is 12" tall with a red lens at the back. Front lens is missing but looks to be a flat one so easily replaced. No dents or dings in this that I see. Please see photos as this is part of the description.
The Dietz Union Driving Lamp would be a great fit for owners of early 1900s vintage cars searching for a high-quality, historically accurate lighting solution for their vehicles.
