Here's mine. It was there when I got the car. It's bolted up under the rear cross-member and also attached to the spreader bar via U-clamps.

I've used it on a number of occasions to tow a 6' x 4' wooden trailer full of garden waste to the dump, but no long journeys. I do have aspirations of towing our teardrop camper with the Model A some day. It weighs around 650kg (1430lb) fully loaded, has a towball weight of around 75kg (165lb) and has self-contained electric brakes. What do you engineers think?
