well Peter, Look at the photos again, since you are so critical of them. There are 3 allen screws, not 4. There is also (2) dowel pins, one on each end to keep it from moving. It is not locally made, It is very obvious that it is a factory produced unit. It's too bad I don't have a camera that will produce a photo to your liking. I guess it is time for you to move along now, and not comment on my post any more. With your high post count, and overwhelming knowledge, and condescending remarks, I'd say, that I don't need your arm chair expertise any more.
